General Safety

Foundations of Engineering and Technology I

Materials

Paint, enamel, lacquer, or solvents must not be used near flames or sparks because they are flammable.

Keep flammable materials in the metal cabinet.

Never leave material lying around someone could get cut, slip, or fall.

Hot metal placed in water can cause the water to be hot enough to burn someone.

Clean Up

ALWAYS CLEAN UP THE LABORATORY

BEFORE YOU LEAVE!!!!

It’s everyone’sresponsibility!

Essential Questions:

1. Why is safety important?2. What are general safety rules to follow?3. What is the proper way to use the lab equipment?4. Where is the safety equipment located?

Why Safety Instruction?

Why Safety Instruction?

Develop an awareness of hazards and become more safety conscious at school, work or at home.

Develop a serious attitude toward the use and practice of safety procedures

To prepare for safety before entering the work area, in the work area, at a workstation and on leaving the work area

To recognize safety symbols, color codes and safety equipment

WHY? Federal, State and

Local Governments pass laws in order to protect citizens (taxpayers)

Schools are responsible to parents for sending kids home in the same condition they arrive each day.

WHY? Private

Agencies/Businesses/Industry are held accountable for providing a safe working environment for their employees.

Private Agencies/Businesses/Industry are held accountable for providing a safe working environment for their employees.

1. (Law suits cut into profits.) 2. Company is less productive

when employees are lost or disabled.

3. Keeping experienced employees safe is more productive and profitable than constantly training replacements.

WHY?

Manufacturers of tools and machines want to avoid lawsuits or recalls from defective products. That’s bad P.R. and will hurt sales. They also want you to come back and buy their products again.

Where Do Most Accidents Happen?

At Home We

Think We’re Safe

and Drop Our

Guard

sense of security can lead

Recognizing Hazards

What is a Hazard?

A hazard is a dangerous situation that could cause an accident.

Three Types of Hazards

Immediate Hazard – A situation that is visible and presents an immediate danger.

Potential Hazard – A situation that is visible but could become dangerous if combined with other situations or events.

Hidden Hazard – An existing dangerous situation that is hidden from obvious view.

Recognizing Hazards

Immediate Hazards

Potential Hazard

Hidden Hazard

Accident Prevention

Accidents can be prevented by…

Identifying and correcting

hazardous situations or conditions

Accidents can be prevented by…

Keeping tools, machines and the work

environment in the best possible condition

Accidents can be prevented by…

Follow ALL Safety Rules Stay Alert Don’t Take Chances IF IN DOUBT….ASK!

Overconfidence is Hazardous

Know your limitations. Get help when necessary.

School Lab Safety The only law affecting work in school labs

is:

Georgia Code 32-4201. This law mandates the wearingof safety goggles by every student, teacher, and visitor participating in or observing chemical, physical, or combined chemical physical activities involving caustic or explosive materials, hot liquids or solids, injurious radiation or other hazards.

Protective Safety Devices

Optional Safety Devices

Protective equipment that is available but the individual must choose to use. It does not work automatically.

Eye Protection

Safety Glasses Eye Glass Side

Shields Goggles Full Face Shields

ALWAYS WEAR EYE PROTECTION WHEN

WORKING IN THE LABORATORY!

Safety Glasses are stored in sterilizing cabinet

Optional Safety Devices

Earphones protect against permanent hearing loss.

Non-Optional Safety Devices

Protective equipment that is operating whether or not we decide to use them.

CAUSES OF ACCIDENTS

80% of accidents are caused by human error.

20% of accidents are caused by unsafe conditions in the surroundings.

What Body Parts Are At Risk

What Causes Most Accidents?

Accidents Take Their Toll Businesses spend $170 BILLION a year on

costs associated with occupational injuries and illnesses – expenditures that come straight out of company profits. In addition Lost productivity from injuries and illnesses costs companies $60 BILLION each year. – O.S.H.A

Auto/Home owners insurance companies rates are higher in some places These factors determine the rates you pay: Where you live (apartments vs home) or drive the most, your sex, age group, your accident record etc.

The higher the risk that they’ll have to pay, the higher your rates will be.

Fire Safety

Three Elements of a Fire

Classifications of Common Fires

Extinguishers are placed in easy-to-see & reach

positions.

Extinguishers receive regular

inspections

Our Fire Extinguishers

IF THE FIRE CAN’T BE PUT

OUT IN15 SECONDS…

Smoke kills more people than the fire

itself.

NEVER USE WATER TO EXTINGUISH:

Flame floats on water / Water conducts Electricity

Both could cause serious injury or death.

Electrical Safety

Safety Around Electricity

Never Overload Circuits

Wires could get hot enough to melt the

insulation and cause a short circuit inside the

wall.

What is a Short Circuit?

Electrons are forced to move through the device when the circuit is working properly

But Electrons will ALWAYS look for the shortest path back to where they came from…even if that means jumping (arcing) between two conductors which could electrocute or

start fires.

Safety Around Electricity

Capacitors inside the back of your TV store

over 10,000 volts and can

electrocute you EVEN WHEN

IT’S UNPLUGGED!!

Tool/Machine Categories

Tools

Always inspect a tool before you use it.

If there is a damaged switch or cord on a power tool report it to your teacher immediately so that the tool can be put up for repair.

Never touch a power tool if it is moving, wait until it comes to a complete stop.

Always use the tool for its proper function.

Using Power Tools in the Laboratory

Always get permission from the teacher before you use the machinery.

Never talk to another student or the instructor while he/she is operating the machinery.

When using the machinery stand only in the “Operator Zone” or the area where only the machinery operator should stand.

Always unplug a power tool by the plug not the cord.

Types of Machines Drill Press – When cutting holes

make sure the material is secured in a Vise or Gripping Tool. Never hold the material.

Band Saw – Use the guide to push material through the blade and keep your hands from the blade. Never force material, forcing means you are trying too hard and could bind.

Scroll Saw – Move material slowly, keep your hand away from the blade.

Sander – Hold material firmly, always move against the spin.

When in the Laboratory…

The Laboratory is a dangerous place if you are not careful.

Never Horse Play. Never Operate the machinery

without checking with the teacher. Loose hair should be tied up,

clothing tucked in, jewelry taken off, and long sleeves rolled up.

If an accident should happen contact the teacher immediately.

Materials

Paint, enamel, lacquer, or solvents must not be used near flames or sparks because they are flammable.

Keep flammable materials in the metal cabinet.

Never leave material lying around someone could get cut, slip, or fall.

Lockout and Tagout

October 30, 1989 – the Lockout/Tagout Standard, 29 CFR 1910.147 went into effect

Intended to reduce the number of deaths and injuries related to servicing and maintaining machines and equipment.

Lockout – the placement of a lockout device on an energy-isolating device to ensure that the equipment being controlled cannot be operated until the lockout device is removed by an authorized person

Utilizes a positive means such as a lock to hold an energy-isolating device in the safe position and prevent the energizing of a machine or device

Tagout – is the placement of a tagout device on an energy-isolating device in accordance with an established procedure to indicate that the equipment being controlled may not be operated until the tagout device is removed

Must warn against hazardous conditions if the machine or equipment is energized and must include a clear warning such as:

DO NOT START. DO NOT OPEN. DO NOT CLOSE. DO NOT ENERGIZE. DO NOT OPERATE

An unplanned event that may or may not result in an injury

Clean Up

ALWAYS CLEAN UP THE LABORATORY

BEFORE YOU LEAVE!!!!

Whether at work or play

one goal to saydon’t let safety bea stranger to thee.

From hazards you can’t tame

you may not look the same.
