CDT Risk Management & Site Safety 3

Question 1

Lockout/Tagout (LOTO) procedures are designed to protect workers from:

Accepted Answer

Unexpected energization or startup of machinery during maintenance

Answer

LOTO procedures (29 CFR 1910.147) ensure that hazardous energy is isolated and cannot be accidentally released while workers service or maintain equipment.

Question 2

A drafting technician is preparing excavation drawings. Per OSHA, which soil type requires the steepest allowable slope (closest to vertical) for a simple slope excavation?

Accepted Answer

Stable rock

Answer

Stable rock may be cut vertically (90°); Type A allows 3/4:1, Type B allows 1:1, and Type C requires the shallowest slope of 1½:1.

Question 3

What is the purpose of a Job Hazard Analysis (JHA) in construction project planning?

Accepted Answer

To systematically identify hazards associated with each job task and determine controls

Answer

A JHA (also called Job Safety Analysis) breaks each task into steps, identifies hazards at each step, and specifies controls to prevent incidents.

Question 4

When reviewing site plans for temporary facilities, which factor is MOST critical for emergency egress planning?

Accepted Answer

Clear, unobstructed paths leading to assembly areas and exits

Answer

Emergency egress requires that exit paths remain clear and wide enough for rapid evacuation, with clear signage directing workers to assembly points.

Question 5

Which type of personal protective equipment (PPE) is specifically required when a drafting technician visits a site where there is a risk of objects falling from above?

Accepted Answer

Hard hat (Class E)

Answer

Hard hats protect against overhead falling objects and are mandatory on most active construction sites; Class E provides electrical protection as well.
