The right and responsibility to stop unsafe work
100
What is the purpose of a machine guard?
To protect from contact with moving parts
100

All employees: From entry-level workers to supervisors, every employee has the authority and responsibility to stop work.
Contractors: Contract workers also have the authority to stop work when they identify an unsafe condition.
Anyone at the site: In practice, anyone observing an unsafe situation is empowered to initiate a stop work command.
200

Lockout/Tagout the equipment
200

300
What is “point of operation” in machine safety?
The area where work is performed on the material — such as cutting, shaping, drilling, or forming
300
What personal behavior most often leads to slip/trip incidents even in safe conditions?
Rushing, distractions (phones), or not watching where you walk
400
What should you do if a ladder label is missing or unreadable?

Always perform Lockout/Tagout (LOTO) and verify zero energy
400

Non-slip mats, grating, or textured surfaces designed for traction.
500
What should you do if you need to reach higher than your ladder allows?
Use the right ladder or equipment — never stack ladders or stand on objects for extra height.
500
What’s the purpose of a “swing fall” hazard check before tying off?
To ensure the anchor point is directly above you — minimizing side-swing impact if a fall occurs.

Unsafe conditions:
Poor lighting or housekeeping
Unsecured work areas
Missing or improperly used personal protective equipment (PPE)
Changes in ground stability or site access
At-risk behaviors:
Working at heights without fall protection
Performing hot work near flammable materials Bypassing safety procedures like lockout/tagout Standing under a lifted load
Equipment issues:
Malfunctioning machinery
Improper use of equipment
Procedural and knowledge gaps:
Changes to the work plan without a new safety review
Lack of sufficient knowledge or training for a task
Witnessing someone not following the correct process
Emergencies:
Fire alarms or equipment failures
A near-miss incident that suggests underlying risks
500

B. Self-adjusting guards are only for woodworking machinery.
C. Guards must prevent body parts from reaching the danger zone during operation.
D. Adjustable guards eliminate the need for Lockout/Tagout.
Answer: C. Guards are designed to prevent any body part from entering the danger zone — regardless of machine type.

A. Footwear design
B. Floor surface material
C. Contaminants (like oil, water, or dust)
