LAWS OF MALAYSIA - Act 514

OCCUPATIONAL SAFETY AND HEALTH ACT 1994

An Act to make further provisions for securing the safety, health and welfare of persons at work, for

protecting others against risks to safety or health in connection with the activities of persons at work, to

establish the National Council for Occupational Safety and Health and for matters connected therewith.

DEFINITION• Human/machine/workplace interaction

• Maximizes quality and efficiency of work• Maximizes human values such as safety,

satisfaction, comfort, learning• These two normally conflict – the need for

juggling skill• Safety - judgment of the acceptability of danger (hazard

& risk) where• Hazard – injury producer• Risk – probability that an injury will occur

• 85 % of accidents caused by human: training is extremely important – to recognize hazard & to work safely

DO’S & DON’TS (1)• Occupational Safety & Health Act 1994

• Control of occupational hazards1. Elimination2. Substitution3. Isolation4. Engineering controls5. Personal protective equipment (PPE)

DO’S & DON’TS (2)• Do’s and Don’ts to prevent accidents

¬ Wear proper attire i.e., workshop jacket & proper shoes. Loose clothing, finger rings and other accessories are some possible sources of accident.

¬ Footwear must be worn all the time to prevent injury – molten aluminum, hot metal chips, slip

¬ Locate the Emergency button or foot pedal. In the event of any accident, switch off the machine using the Emergency button.

¬ Never let anyone handle the starting switch for you.

¬ Ensure work-pieces are properly clamped or secured to the machine. Remove any loose parts such as chuck key, vice handle, etc. – flying chuck key (faint) & flying work-piece

¬ Always wear goggles where fine chips are produced – bloated eye.

DO’S & DON’TS (5)• Do’s and Don’ts to prevent accidents

¬ Use machine guards all the time.¬ When you are operating any machine, stand

at a proper distance.¬ Do not use hand(s) or finger(s) to stop moving

or rotating machines or parts of machines – legs between rollers

¬ Do not set the tools when the machine is running. You may break the tool and worse still, you may injure yourself.

¬ Never handle machines or work-pieces during running. Stop the machine first…

DO’S & DON’TS (6)• Do’s and Don’ts to prevent accidents

¬ Do not distract a person while he or she is operating a machine. Wait till he or she completes the operation & stop the machine before doing so – Do not be playful – NO PRACTICAL JOKES

¬ Do not use hands to clear metal chips – 600 ~ 700OC (chip-tool interface)

¬ Do not take measurement while machine or work-piece is moving

¬ Do not blow chips, dust from vices, etc. lest they may get into your eyes.

DO’S & DON’TS (7)• Do’s and Don’ts to prevent accidents

¬ When facing with problems or uncertainty, stop the machine & get clarification and help.

¬ Stop any machine before leaving it. Never leave any machine running unattended.

¬ Beware of high temperatures associated with metal chips, welding, heat treatment & casting activities

¬ Beware of high voltages. Ensure all machines are properly earthed. Do not interfere with electrical equipment or connections.

DO’S & DON’TS (8)• Do’s and Don’ts to prevent accidents

¬ Protect your eyes from bright lights & ears from loud sounds

¬ Plan your time properly. Working under unnecessary pressure may lead to accidents

¬ Grinding tools must be set up by experienced personnel. Grinding tools rotate at great circumferential speed

¬ Damaged grinding tools & wheels must not be used

¬ Do not run any machining exceeding the maximum allowable speeds

¬ Beware of sharp or ragged edges

DO’S & DON’TS (9)• Do’s and Don’ts to prevent accidents

¬ Report any injury, cut or scratch, no matter how trivial it may be to your instructor

¬ Clean the tools, cutters, machines & surrounding area from debris, metal chips, oils, grease & coolants whenever necessary and after completing your work

Clean working + good order = safety¬ Return all tools to store or original cabinet¬ Never handle heavy objects unaided.

ELECTRICAL SAFETY

Slips, trips, and falls account for more workplace injuries annually than any other accident category. Many of these injuries can be disabling, or even fatal.

ILLUSTRATIONS (4)Danger of working with machinery

Minimizing risks by proper installation and use of safety guards and devices.

The risk of accidents from powered machinery is so great OSHA estimates that lack of machine guarding is the second most frequent safety violation in industry today.
