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.

“You won’t believe the bad luck I just had….”
Where Do Most Accidents Happen?
At Home We
Think We’re Safe
and Drop Our
Guard
…and that false
sense of security can lead
to an Accide

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.

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
What is an Accident?
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.
