CONSIDER THE SCENARIO

Donesha walked into the class television studio around 7am this morning, and noticed that all of the studio lights were still

turned on. She went to turn them off, and tripped on a cord that was in her pathway. The fall was made worse by the fact that

she knocked over a half-empty cup of coffee that was sitting on the ground. She filed for worker’s compensation, and an

inspector from OSHA came out to review the cause of the fall. Who is at fault for this accident? What went wrong? What could you learn from this? Jot your thoughts on a sheet of paper and be prepared to share them with the rest of the

class…

SOMETHING DOES SPILL, UNPLUG THE COMPUTER AND

NOTIFY ME IMMEDIATELY.

RUNNING & HORSEPLAYING

Using Electricity• Do not use equipment with damaged

cords.

• Never use electrical equipment on a wet surface.

• Keep equipment dry.

• Do not touch electrical switches or equipment

with wet hands.10

Stay away from exposed wires!

ELECTRICAL BURNS

BROKEN CAMERA OR EQUIPMENT

CONTACT TEACHER IMMEDIATELY!

Protecting Your Hearing

• If you must shout to be heard from three feet away, the noise is too loud; hearing protection should be used.• Decibels: Over 115 decibels -- unsafe.• Hearing damage is permanent.

GOOD POSTURE

POSTURE

TECHNIQUE

PROPERFURNITURE

Workstations• Keyboard and work surfaces –

arms should form a 90-degree angle.

• Top of the monitor – no higher than eye level.

• Chairs – comfortable backrest, feet should be flat on the floor.

• Chairs or stools should never be leaned or tilted back.


17

PROPER LIFTING TECHNIQUE

Lifting and Carrying

• Size up the load• Think before you lift• Obtain help• Balance the load• Carry less, more times (make several trips)• Lift using your leg muscles – not your back (don’t bend over)


19

Maintenance

• Clean your work area before the end of the period.

• Return equipment to approved locations.

• Floors must be free of objects that might cause falls.

STUDIO LIGHTING

IT’S HOT!

EQUIPMENT CAN OVERHEAT

Fire Safety• Type A fires – combustible materials, paper, cloth,

wood• Type B fires – flammable liquids, solvents, oil• Type C fires – electrical equipment or electrical wires.• Using the wrong type of extinguisher on the wrong type of fire can be dangerous• PASS method Pull the pin, Aim low, Squeeze the handle, Sweep from side to side.


23

Using a Fire Extinguisher

Pull the Pin at the top of the extinguisher. The pin releases a locking mechanism and will allow you to discharge the extinguisher.

Aim at the base of the fire, not the flames. This is important - in order to put out the fire, you must extinguish the fuel.

Squeeze the lever slowly. This will release the extinguishing agent in the extinguisher. If the handle is released, the discharge will stop.

Sweep from side to side. Using a sweeping motion, move the fire extinguisher back and forth until the fire is completely out. Remember: Aim at the base of the fire, not at the flames!!!!

In Case of an Accident

• Immediately report accidents to the teacher.• The school nurse should treat injuries.


25

Human Error

• The one element common to

most accidents.

• Not applying common sense

is the cause of most

accidents.

Soldering 101

A Really HOT Topic

Soldering

The process of making an electrical connection by melting low-temperature metal alloys around component leads

Soldering is just as much an “Art” as it is a “Science”

We will: Go over some soldering vocabulary Illustrate graphically soldering techniques Solder a few components on the TV Remote board Complete the board as homework

Soldering Iron Safety

Never touch the element or tip of the soldering iron. They are very hot (about 400°C) and will burn.

Hold wires to be heated with tweezers or clamps.

Keep the cleaning sponge wet during use. Always return the soldering iron to its stand

when not in use. Never put it down on your workbench.

Turn unit off or unplug it when not in use.

Working Safely with Solder

Work Safely with Solder, Flux and Cleaners Wear eye protection. Solder can “spit”. Use lead free solder. Keep cleaning solvents in dispensing bottle to

reduce inhalation hazards. Always wash your hands with soap and water

after soldering. Read and understand the MSDS for all materials

before beginning work.

Dangers of Lead Exposure

Lead on your skin can be ingested and lead fumes can be given off during soldering. Other metal fumes can also be hazardous. Lead can have serious chronic health effects, such as:

Reproductive problems digestive problems nerve disorders memory and concentration problems muscle and joint pain

Avoiding Toxic Fumes

Work in a well-ventilated area. The smoke formed is mostly from the flux which can be irritating, a sensitizer and aggravates asthma.

Avoid breathing it by keeping your head to the side of, not above, your work.

A benchtop fume extractor may be necessary to remove harmful fumes caused by solder and flux from the soldering workstation by filtering the air.

Fire Prevention

Work on a fire-proof or nonflammable surface that is not easily ignited.

Wear nonflammable or 100% cotton clothing that covers your arms and legs to help prevent burns.

Know where your fire extinguisher is and how to use it.

First-Aid

• Immediately cool the affected area under cold water for 15 minutes.

• Do not apply any creams or ointments. Cover with a band-aid.

• Seek medical attention if the burn covers an area bigger than 3 inches across.

IF YOU HAVE ANY QUESTIONS OR CONCERNS, ASK ME!
