Hazardous materials
(HAZMATs)
GHS• Abu Dhabi uses the Globally Harmonised System of
Classification and Labelling of Chemicals (GHS) • The UN brought together experts from different
countries to create the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) to minimise confusion over labels.
• The aim of the GHS is to have, worldwide, the same: criteria for classifying chemicals according to their health,
environmental and physical hazards; and hazard communication requirements for labelling and safety
data sheets.
GHS
GHS uses:Symbols & pictogramsSignal words, e.g. DANGER; WARNINGHazard statements, e.g. fatal if swallowed Precautionary statements (see next slide)
Precautionary statements
• Precautionary statements are also required by the GHS to describe the following:PreventionResponse (in case of accident)Storagedisposal
Precautionary statements Prevention Response Storage Disposal
Avoid breathingspray.In case of inadequate ventilation wearrespiratory protection.
IF INHALED: If breathing is difficult,remove to fresh air and keep at rest in a position comfortable for breathing.If experiencing respiratory symptomscall a POISON CENTER or doctor.
Store away from children at less than 30⁰C.
Dispose of unused contents in landfill waste. Do not pour contents down the drain.
LD50 & LC50• What does LD50 mean? • LD stands for "Lethal Dose". LD50 is the amount of a material,
given all at once, which causes the death of 50% (one half) of a group of test animals. The LD50 is one way to measure the short-term poisoning potential (acute toxicity) of a material.
•What does LC50 mean?
• LC stands for "Lethal Concentration". LC values usually refer to the concentration of a chemical in air but in environmental studies it can also mean the concentration of a chemical in water.
• For inhalation experiments, the concentration of the chemical in air that kills 50% of the test animals in a given time (usually four hours) is the LC50 value.
Acute toxicity -Oral
Pictograms are important in labelling
HAZMATs
Corrosive
Harmful
Toxic; may be fatal
Unstable explosive
Extremely flammable
Gas under pressure; may explode when heated
May cause breathing problems
Toxic to the environment
GHS uses 5 categories to show danger

Hazardous materials management
CoP aims
• Give practical advice to manage HAZMATs
• Drive improvement
• Address deleterious impacts of HAZMATs
Intent
• Reduce environmental harm• Encourage efficient use of resources• Enhance OHS• Identify roles & responsibilities of
manufacturers, importers, suppliers, employees, employers & community re. HAZMATs
• Introduce penalties for non-compliance
Environment, Health & Safety Impact Assessment
EHSIA
Required prior to obtaining permit
IA must say how discharges will comply with CoPs (air, water, land & noise)
IA must describe plans for future rehabilitation of site
HAZMATs Management indicators
Class 1 – health, safety, wellbeing
Class 1A – general provisions for HAZMATs management
Class 1B – specific provisions for HAZMATs management
Class 1A management indicators
All HAZMATs to be classified according to GHS
Manufacturers, Importers & Suppliers of HAZMATs must:
prevent or minimise wastehave permitsclassify & label all HAZMATsStore, handle, transport and dispose of all
HAZMATs properlyprepare MATERIAL SAFETY DATA SHEETS (MSDS)http://avogadro.chem.iastate.edu/MSDS/methane.pdfdisclose ingredients to medics, Sector regulators
and EAD
Employers must:
label and maintain a register of all HAZMATscarry out a risk assessmentensure exposure standards are not exceededensure routine health checks for employees
and make records availableKeep all relevant recordsMake MSDS available to employeesTrain employees & provide safety equipment
Employees must:
Comply with CoPs as much as possible
Inform the employer where non-compliance is evident
EAD must:
• Provide direction (GHS)• Ensure compliance with waste CoP• Establish lines of communication regarding
HAZMATs with concerned parties and the community
• Undertake inspections & audits• Penalise those who are non-compliant
1B Indicators
To be classified as:Physical hazards, e.g. explosives; flammable
substances; corrosive substancesHealth hazards, e.g. carcinogenic, mutagenic,
toxicEnvironmental hazards, e.g. hazardous to
aquatic environment
• Incidents involving HAZMATs must be reported
• Transporters of HAZMATs must maintain written or e-records
• EAD to develop an emergency response
