1. SUMMARY OF THE HEALTH AND

SAFETY IN EMPLOYMENT ACT 1992

1.1 Introduction

During 1991 and 1992, the Government introducedvarious legislation in the labour market area which hadthe common theme of moving responsibility andaccountability away from central government into theindividual workplace.

Employers are now required to manage their ownworkplaces in line with legislation which is basicallyself-regulatory. The style can be seen in the EmploymentContracts Act, the Accident Rehabilitation andCompensation Insurance Act, the Industry Training Actand the Health and Safety in Employment Act.

1.2 Objective

The principal objective of the HSE Act is to preventharm to employees at work. To achieve this, it imposesduties and responsibilities on employers, employees,principals and others, and promotes excellent health andsafety management by employers.

1.3 Regulations

Regulations impose duties and responsibilities onemployers, employees, designers, manufacturers andothers relating to health and safety. These regulationsapply to places of work, plant, processes or substancesand may be made to deal with specific problems thathave arisen.

Health and Safety Issues in the New Zealand Lift Industry 9

1.4 Approved Codes of Practice

The HSE Act provides for the use of approved codes ofpractice. They are statements of preferred workpractices, and may include other procedures that couldbe taken into account when deciding on practical stepsto be taken. Compliance with codes is not mandatory,however it may be used as evidence of “good practice”in court.

1.5 Employers’ Duties

Employers are required to take all practicable steps toensure that the safety of employees at work is notcompromised, they are required to take all practicablesteps to:

• Provide and maintain a safe work environment;

• Provide and maintain facilities for the health andsafety of employees at work;

• Ensure that machinery and equipment is safe for allemployees;

• Ensure that working arrangements are nothazardous to employees; and

• Provide procedures to deal with emergencies thatmay arise while employees are at work.

Taking “all practicable steps” means doing what isreasonable and able to be done in the circumstances,taking into account:

• The severity of any injury or harm to health thatmay occur;

10 Health and Safety Issues in the New Zealand Lift Industry

• The degree of risk or probability of that injury orharm occurring;

• How much is known about the hazard and ways ofeliminating, reducing or controlling it; and

• The availability, effectiveness and cost of possiblesafeguards.

1.6 Hazard Management

Employers must identify and regularly review hazardsin the workplace, this includes existing, new andpotential hazards, to determine whether they aresignificant and require further action. If an accident orharm occurs that requires particulars to be recorded,employers are required to investigate and determinewhether it was caused by, or arose from, a significanthazard.

“Significant hazard” means a hazard that is an actual orpotential cause or source of:

• Serious harm; or

• Harm (being more than trivial) where the severityof the effects on any person depends (entirely oramong other things) on the extent or frequency ofthe persons exposure to the hazard; or

• Harm that does not usually occur, or is not usuallyeasily detectable, until a significant time after theexposure to the hazard.

Where the hazard is significant, the HSE Act sets outthe steps employers must take:

Health and Safety Issues in the New Zealand Lift Industry 11

• Where practicable, the hazard must be eliminated.

• If elimination is not possible, the hazard must beisolated.

• If it is impractical to eliminate or isolatecompletely, then employers must minimise thehazard to employees.

• Where the hazard has not been eliminated orisolated, the employer must, where appropriate:

- ensure protective clothing and equipment isprovided, accessible and used;

- monitor employees’ exposure to the hazard;

- seek the consent of employees to monitor theirhealth; and

- with their consent, monitor employees’ health.

1.7 Information for Employees

Employers are required to inform employees of anyhealth and safety monitoring. In doing so, the privacyof each employee must be protected.

Before employees begin work, they must be informedby their employer of:

• Hazards employees may be exposed to while atwork;

• Hazards employees may create which could harmthemselves or other people;

• Ways to minimise the possibility of becoming asource of harm to themselves or others;

12 Health and Safety Issues in the New Zealand Lift Industry

• The location of safety equipment; and

• Emergency procedures.

1.8 Employee Involvement in Developing

Health and Safety Procedures

Employees shall be given the opportunity to be fullyinvolved in the development of procedures for thepurpose of identifying hazards and dealing withsignificant hazards, or dealing with or reacting to,emergencies and imminent dangers.

1.9 Training of Employees

Employers must ensure employees are eithersufficiently experienced to do their work safely, or aresupervised by experienced people. In addition,employees must be adequately trained in the safe useof equipment in the place of work, including the use ofprotective equipment and clothing.

1.10 Safety of People Who Are Not

Employees

Employers are responsible for the health and safety ofpeople who are not employees. Employers must takeall practicable steps to ensure that employees do notharm any other person while at work, includingmembers of the public or visitors to the workplace.

Health and Safety Issues in the New Zealand Lift Industry 13

1.11 Employees and Self-Employed Persons’

Duties

Employees and self-employed persons are responsiblefor their own health and safety while at work. Theymust ensure that their actions do not harm anyone else.These responsibilities do not detract from employers’or principals’ duties and responsibilities.

1.12 Accident and Serious Harm

The HSE Act requires employers to keep a register ofwork-related accidents and serious harm. This shallinclude every accident that harmed or might haveharmed:

• Any employee while at work; and

• Any person in a place of work under the employer’scontrol.

Employers are also required to investigate allaccidents, harm or near-misses to determine whetherthey were caused by a significant hazard.

Employers must notify all cases of serious harm toemployees while at work to the Secretary of Labour (inpractice the nearest OSH office), as soon as possible.In addition, the accident must be reported on theprescribed form within 7 (seven) days. (Forms areincluded in the Workplace Accident Register availablefrom OSH offices and selected stationers.)

If a person suffers serious harm, the scene of theaccident must not be disturbed unless to:

• Save life or suffering;

14 Health and Safety Issues in the New Zealand Lift Industry

• Maintain public access for essential services, e.g.electricity, gas; or

• Prevent serious damage or loss of property.

The OSH office will advise whether it wishes toinvestigate the accident and what action may be takenin the meantime.

2. INTRODUCTION

The requirements specified in this code are intended toserve as the basis upon which elevator businessesthroughout the country can build comprehensive jobsite safety programmes that reflect individual operatingneeds. These minimum standards of performanceprovide a mandatory framework for each company tofulfil its obligation to provide its employees with aworkplace free from recognised occupational hazards.

This procedure is focused on establishing andmaintaining effective safety management systems andspecifying key mandatory work rules designed tomitigate the possibility of injury or illness fromhazards common to our industry.

Some clauses in this code make provision foralternative methods that can be used.

If a company wishes to use alternative methods, thenthe company must have a documented procedure forreviewing, approving and recording the alternativesolutions. No alternative method shall be used unless ithas undergone this procedure.

16 Health and Safety Issues in the New Zealand Lift Industry

3. SCOPE

The standards apply to all job sites, and describemandatory safe working provisions and practices(supported by training) for all companies responsiblefor and involved in the installation, examination,inspection, testing, manufacturing, service,maintenance, repair and dismantling (includingcomplete demolition) of elevators, escalators andassociated equipment.

The safe practices specified herein apply to all aspectsof the work environment and reflect collectiveexperience in the elevator, escalator and people-moving equipment business and the constructionindustry.

Health and Safety Issues in the New Zealand Lift Industry 17

4. SAFETY MANAGEMENT SYSTEM

Each company must develop and implement a formalsafety management system that includes, at aminimum, the following elements:

4.1 Statement of Policy

A policy statement that clearly communicates thecompany’s commitment to the prevention of accidentsmust be written. The policy must be reviewed annuallyand updated as required.

4.2 Accountability

Each operating/line manager and/or supervisor will beheld accountable for all aspects of the safetyprogramme. Written safety objectives are to bedeveloped, clearly communicated and used as a basisfor performance evaluations and “pay-for-performance” programmes.

4.3 Hazard Identification and Control

Each company shall conduct a systematic analysis ofworkplace and job site risks and then develop andimplement controls for the identified hazards. Thisprocess shall be accomplished at least once a year.

Prior to the signature of any new contractualagreement (including maintenance, new equipment,modernisation, and open order work), a riskassessment must be made of the work to be done andconditions of the job site. Based on the results of this

18 Health and Safety Issues in the New Zealand Lift Industry

assessment, prevention and/or control measuresnecessary to safeguard identified hazards and risksmust be established. For new construction sites, whereaccess to the site or location is not possible, theassessment process must anticipate probable risks/hazards.

Control measures that are not the direct responsibilityof the company must be specifically identified and putforth as requirements to the building owner, generalcontractor and/or sub-contractor as applicable.

4.4 Safety Education and Training

Specific employee training and education initiativesmust be developed to address inherent risks present atall workplaces and job sites. All operating/linemanagers, supervisors and sales and marketingpersonnel must participate in training programmes toimplement and enforce safety programmerequirements.

4.5 Communication

Mechanisms must be established to facilitatecommunication among all employees in effectivelyconveying management’s commitment to theprevention of accidents and to ensure receipt ofinformation necessary to perform functions andenhance awareness of safety issues. Communicationvehicles such as employee meetings, companynewspapers, bulletin boards, and supervisor dialogueswith workers are examples of the many channels that

Health and Safety Issues in the New Zealand Lift Industry 19

can be used to meet these objectives.

4.6 Health and Safety Rules

Health and safety rules must be developed,documented and consistently applied to all aspects ofthe job. These rules must be reviewed with allpersonnel and are an important part of training newemployees. Once established, health and safety rulesmust be enforced by line management.

4.7 Enforcement Programmes and

Disciplinary Procedures

Enforcement programmes and disciplinary proceduresmust be formally documented and consistently appliedat all levels of the organisation. Disciplinary actionshould be based on the seriousness of the violation andrange from a verbal warning to job termination.

4.8 Maintenance of Safe Working

Conditions

Routine job site safety inspections must be made by alllevels of line supervision. These inspections will bedesigned to evaluate the effectiveness of the safetyprocedures. All inspection deficiencies must bedocumented and a corrective action plan developedwhich assigns responsibility and establishes atimetable for completion.

4.9 Measurement of Effectiveness

A comprehensive evaluation of the safety system must

20 Health and Safety Issues in the New Zealand Lift Industry

be accomplished at least once a year to determine itseffectiveness in achieving established goals. Thisevaluation must include a review of all accidents andtheir causes.

Health and Safety Issues in the New Zealand Lift Industry 21

Health and Safety Issues in the New Zealand Lift Industry 33

5.9.3. A policy must be developed and implementedso as to limit the number and assignment ofjumpers. The number of jumpers assigned toeach person must be based on the work to bedone and must be controlled by each supervisor.A signed record of receipt must be maintained.

5.9.4. Procedures must be established to control allaspects of the work. At a minimum, thefollowing precautions are required:

a) The affected elevator/equipment must betaken out of service for public use.

b) Before placing jumpers on door locks andsafety circuits, ensure that the car can onlyoperate on slow/inspection speed.

c) To alert other employees as to the use ofjumpers, a warning tag shall be attached toeach jumper in use. In addition, a warningsign shall be placed on the cover of thecontroller which indicates that a jumper(s) isin use. This warning shall identify theemployee placing the jumper, date placedand the serial number of the jumper in use.Verbally notify other affected personnel ofthe circuit and the location where jumpersare being used. Upon removal, jumpers shallbe matched to the serial numbers to ensureremoval of all jumpers.

d) A personal reminder control (e.g. key bag,tag on tool box, badge clipped to shirt, etc.)

34 Health and Safety Issues in the New Zealand Lift Industry

shall be used by each employee placing ajumper such that it will require the employeeto return to the machine room to remove thejumper.

e) If working in a hoistway, an emergency stopmechanism shall remain in effect. Forexample, never jump out the hoistway doorlocks and the car door locks at the sametime.

f) For maintenance and repair operations,jumpers shall be removed whenever themechanic relinquishes the job task toanother employee. For all operations, alljumpers must be removed before placing theelevator into service or back into service tothe public.

5.9.5. It is preferable that new elevators be designedsuch that an elevator must automatically beplaced on inspection mode before it can bemoved with a jumper on the door contacts.

Health and Safety Issues in the New Zealand Lift Industry 35

6. ELEVATORS

6.1 Working in the Hoistway

6.1.1. To gain access to the hoistway via landingdoors, with the car situated at some convenientdistance away from its normal position at alanding, an approved unlocking device oraccess key switch shall be used to unlock alanding door.

Before the door is opened for access, it must bedecided if the work to be done will require theelectrical power supply. If not, the main lineswitch must be in the “off” position (or thefuses must be withdrawn and retained in asecure place) and an appropriate lockout/tagoutdevice shall be attached to the main line switch.

6.1.2. Before entering the hoistway a safe means ofentry and exit from the hoistway must beclearly established.

6.1.3. Landing doors must not remain open longerthan absolutely necessary.

6.1.4. Simultaneous work must not be conducted inthe hoistway by employees or others, whereindividuals or groups would be workingindependently of each other and/or where theworkers are stacked in the hoistway (i.e. above/below each other.)

CAUTION: No more than two persons will bepermitted to work in each individual hoistway

36 Health and Safety Issues in the New Zealand Lift Industry

at the same time. Any exception to this willrequire personal review and writtenauthorisation from the installation or servicemanager.

6.1.5. After completion of work, an elevator must notbe returned to normal operation until it has beenconfirmed that all workers, tools and equipmentare clear or have been removed from thehoistway.

6.2 Working on the Car Top

Before attempting to gain access to the hoistway, itshould be decided if the work to be done will requirethe electrical power supply. If not, the main line switchmust be tagged and locked in the “off” position (or thefuses must be withdrawn and retained in a secureplace) and an appropriate lockout/tagout device shallbe attached to the main line switch.

6.2.1. If it is necessary for the electrical power supplyto the car to be maintained for the work to beperformed, use the following procedures:

a) The elevator must always be run in theinspection mode. Any deviation from thisprocedure will require written authorisationfrom the managing director or companyowner.

b) Safe procedures must be established foraccessing and exiting the car. Theseprocedures must include a safe method forcapturing the car, taking and verifying

control prior to getting on top of the car andmaintaining control until safe egress hasbeen achieved.

6.2.2. Fall protection must be provided at all timeswhen a fall hazard exists when working on topof the car.

6.2.3. All elevators under maintenance contract willbe provided with a car top inspection station.All such fixtures shall be provided with acommon button and direction buttons wired sothat both the common and a direction buttonmust be depressed to operate the car.

When it is necessary for personnel to travel ontop of a car, this inspection station must befixed in place and checked for proper operationbefore proceeding with the work. (Down travelis safer than up travel.)

6.2.4. When work is being performed on top of the carin a common hoistway, a protective device mustbe installed to cover the height and width of theexposed work area to protect employees fromadjacent moving equipment.

6.2.5. Additional precautions include:

a) Never wear anything that could catch ortangle while on top of a moving car. Nevercarry tools in pockets. Guardrails shall beused wherever possible where a fall hazardexists. As a general rule, harnesses andlanyards should not be worn while moving a

car on inspection. However, if unusualconditions require the use of this form of fallprotection, then the following precautionsmust be followed:

i. When the elevator is placed on inspectiondrive from the car roof top controlstation, it may only be returned to normalservice by the operation of that sameswitch.

ii. A hazard analysis must be conducted andsteps taken to ensure that the harness orlanyard can not become entangled orsnagged. (Lanyards must be disconnectedfrom harness during travel.)

b) Ensure provision of a clean flat surface tostand on that will support the weight ofpersonnel and equipment. Incorporate theuse of special care when car tops are curvedor domed.

c) To eliminate the possibility of falling whileriding a moving car, always take a positionnear the centre of the car and maintain a firmhandhold on the crosshead away frommoving parts.

d) Tools and other equipment required for thejob are to be temporarily place on the cartop, safely positioned away from the edge ofthe car.

e) Do not store material of any nature on top ofthe car.

Health and Safety Issues in the New Zealand Lift Industry 39

f) Never hang an electric extension light fromthe hoist ropes.

g) Keep your body within the limits of theelevator hoistway being inspected. Accidentsfrom adjacent moving elevators can occur.Be aware of the counterweights position atall times, including adjacent lifts.

6.2.6. The headroom above the car must be displayedin a prominent position, preferably near the cartop control station to visually indicate theminimum overhead clearance.

6.2.7. All persons working in the hoistway must beaware of when and how the car is to be moved.It is also essential that only one person be incontrol. Each company must develop acommunications procedure to be used bypersonnel working together in the hoistway.(See Appendix 9.4 for industry-recommendedcommunication terms.)

6.3 Working in the Pit

Entry into the pit will only be permitted when twoindependent means of shutting off the elevator areavailable and used. For example, the use of anemergency stop switch and opening the door lock.

Where a redundant means of protection is notavailable, the main line switch must be tagged andlocked in the off position (or the fuses should bewithdrawn and retained in a secure place).

40 Health and Safety Issues in the New Zealand Lift Industry

Occupational Overuse Syndrome (OOS): this termhas officially replaced that of repetitive strain injury(RSI) in New Zealand.

Definitions as described in the Health and Safety InEmployment Act 1992:

“Accident” means an event that—

(a) causes any person to be harmed; or

(b) in different circumstances might have caused anyperson to be harmed.

“Employer” means a person who or that employs anyother person to do any work for hire or reward: and, inrelation to any employee, means an employer of theemployee. This means anyone who supervises others iseffectively an employer.

“Employee”, subject to subsection 2(3) of the Act,means a person employed by any other person to doany work (other than residential work) for hire orreward; and, in relation to any employer, means anemployee of the employer.

“Harm” means illness, injury or both; and “to harm”,“harmed” and “unharmed” have correspondingmeanings.

“Serious harm”, subject to subsection (4) of the HSEAct section, means death, or harm of a kind ordescription declared by the Governor-General byOrder in Council to be serious for the purposes of thisAct; and “seriously harmed” has a correspondingmeaning.

60 Health and Safety Issues in the New Zealand Lift Industry

“At work”, in relation to any person, means present,for gain or reward, in the person’s place of work.

“Hazard” means an activity, arrangement,circumstance, event, occurrence, phenomenon,process, situation or substance (whether arising orcaused within or outside a place of work) that is anactual or potential cause or source of harm; and“hazardous” has a corresponding meaning.

9.4 Terminology

Clear, concise, correct communication is VITAL TOTHE SAFETY OF ALL CONCERNED.

Words that fit this category are:

• GO UP

• COME DOWN

• STOP

• ARE YOU CLEAR?

• OK

• YES

• NO

Be specific about how far the lift car is to be moved.Vague instructions create problems.

Prior to starting, go over instructions to be used withthe people involved.

A team member, regardless of their position, must notfeel inhibited about querying an instruction oracknowledgement if it is not fully understood or seemswrong.

Anybody who is unsure of what they are about to do ordoes not feel safe carrying out that instruction, eitherbecause they have misinterpreted what is required orthey do not know how to do what is required, shouldask. It may be, in fact, a poor or bad instruction.

Either way it is liable to end up being dangerous orworse still, a disaster.

Health and Safety Issues in the New Zealand Lift Industry 63

If you mean, for example, that you only want theequipment to move up, say so.

e.g. GO UP 25 mm,GO UP 300 mm,COME DOWN 150 mm.

The terminology used in the issued instruction shouldbe used in the repeat of that instruction.Acknowledgement shall be when the issued instructionis considered to have been fully understood.

BE CLEAR ABOUT WHAT YOU MEAN!!

The person moving the lift car must ask the question:

“ARE YOU CLEAR?”

and wait for a “YES” or “OK” answer before movingthe equipment. The driver must remain ALERT and beprepared to stop immediately on the slightestindication that all is not well.

There can be NO EXCEPTION TO THE RULESregarding the 4 Cs.

• CLEAR

• CONCISE

• CORRECT

• COMMUNICATION

The importance of the 4 Cs cannot be overstated,particularly when we are an industry of multinationalpeople.

When a lift car has been correctly positioned, addedsafety can be achieved by tripping any ‘knock off’ type

64 Health and Safety Issues in the New Zealand Lift Industry

safety switch so that accidental movement of the liftcar is prevented. Switches that can be tripped and usedfor this purpose are:

• Overspeed grips switch (safetiesoperated switch) if accessible;

• Broken tape switch (when used);

• Compensation sheave switch (whenused);

• Pit stop/run switch; and

• Main switch — locked and tagged out.

e.g. On completion of the work in the lift shaft gettingout or exiting the lift shaft is every bit as important inrespect to safe practices as for getting into the shaft inthe first place.

NOTE: The lift car must always be operated oninspection mode when working in a lift shaft:

- Tell the assistant you are going to get out.

- Advise the assistant that you will stop them byyour operation of the Pit Stop/Run Switch.

- Advise assistant to reset the tripped switches, ifapplicable.

- Instruct assistant to take lift car up “x” numberof floors. Do not come down until instructed todo so.

- Communicate as above, e.g. “Are you clear?”,etc.

i.e. When the lift car has been taken up a suitable

Health and Safety Issues in the New Zealand Lift Industry 65

distance set the stop/run switch to stop — the car muststop at the same time.

- Advise your assistant, that you are opening thelanding doors.

- Remove the tools, etc. on to the landing.

- When clear of the lift pit reset the pit switch torun.

- Instruct assistant to bring car down so that theunder car light can be turned off.

- Close the landing doors.

- Open hoistway doors when lift car has beenpositioned halfway down entrance to turn offthe under car lights.

Arrange to meet your assistant on the next floor so thatthe job can be completed.

Remove any circuit jumpers. Record as necessary.

- Re-test that all safety circuits are operational.

- Turn off the hoistway lights.

- When satisfied, return the lift car to full service.

Remember this:

It is as much your responsibility to maintain yoursafety as it is your supervisor’s to ensure that youknow how to go about your duties in complete safety.

If you have any doubts, it is your responsibility to say:

“I don’t understand”. “I’m not sure how to go aboutit”.

66 Health and Safety Issues in the New Zealand Lift Industry

There is no room for guess work and “she’ll be right”has no place in our industry.

While we have discussed the pit situation here,demanding ‘clear, concise, constant communication’,the same is required for:

- Hoistway/inside car;

- Machine room/sub floor;

- Machine room/pit (basement layout); and

- Escalator/moving walkway work.

You have all been, or should have been issued with thered and green Lift Industry Accident PreventionHandbook. This book is full of useful tips and goodinformation about safety. It is designed to fit in yourpocket for ready reference when needed. Pages 8through to 16 cover safety:

- In the machine room;

- In the pit;

- In the lift well;

- With hydraulics;

- With escalators and moving walkways; and

- Electricity.

If you do not have a copy, ask your supervisor for one,it was compiled for the industry.
