Question 1

What is the purpose of a Safety Data Sheet (SDS)?

Accepted Answer

To provide detailed information on chemical hazards, safe handling, and emergency response

Answer

An SDS (formerly MSDS) is a standardized document providing workers and emergency responders with information on chemical properties, hazards, safe handling, and first aid.

Question 2

In accident causation, what does the 'domino theory' proposed by H.W. Heinrich suggest?

Accepted Answer

A sequence of five factors (ancestry → fault → unsafe act/condition → accident → injury) causes workplace injuries

Answer

Heinrich's domino theory models injury as the final domino in a chain: social environment, fault of person, unsafe act or condition, accident, and injury.

Question 3

What does the term 'incidence rate' mean in occupational health metrics?

Accepted Answer

Number of injury/illness cases per 100 full-time employees per year

Answer

OSHA's incidence rate = (number of cases × 200,000) / total hours worked, normalizing data to 100 full-time equivalent workers for comparison.

Question 4

What is 'confined space' entry hazard and what makes a space 'permit-required'?

Accepted Answer

A space large enough to enter but not designed for continuous occupancy, containing atmospheric, engulfment, or entrapment hazards

Answer

A permit-required confined space has one or more serious hazards (hazardous atmosphere, engulfment risk, converging walls, or other recognized hazards) requiring a written entry permit.

Question 5

What is the purpose of a 'toolbox talk' in a safety program?

Accepted Answer

A brief, informal safety meeting held at the job site to discuss current hazards and safe work practices

Answer

Toolbox talks are short, focused safety discussions held before work shifts to reinforce safe practices, address current hazards, and maintain safety awareness.
