Under what wind speed condition should a stormwater site supervisor halt crane or lifting operations near detention pond embankments?
Answer: 30 mph
Most crane manufacturers and OSHA guidelines recommend halting lifting operations when sustained winds exceed 30 mph to prevent load swing and equipment instability.
Which OSHA standard specifically governs excavation and trenching safety for stormwater pipe installation work?
Answer: 29 CFR 1926.650–652
29 CFR 1926.650–652 is OSHA's Subpart P governing excavation and trenching safety, which applies to stormwater pipe and infrastructure installation.
Hydrogen sulfide (H2S) gas in stormwater manholes is most dangerous because it:
Answer: Deadens the sense of smell at concentrations that are immediately dangerous to life
H2S paralyzes olfactory nerves at high concentrations, eliminating the worker's ability to smell it as a warning signal at IDLH levels (100 ppm).
During a stormwater site emergency requiring evacuation, what is the first step in the Incident Command System (ICS) response?
Answer: Establish command and account for all personnel
Under ICS, the first priority in any emergency is establishing incident command and performing a personnel accountability check to confirm no one is unaccounted for.
What minimum illumination level (in foot-candles) does OSHA recommend for construction areas where stormwater workers are performing general work tasks?
Answer: 5 foot-candles
OSHA 29 CFR 1926.56 requires a minimum of 5 foot-candles of illumination for general construction and work areas.
A stormwater crew is working in a traffic zone adjacent to a highway. Which item of high-visibility PPE is required by the MUTCD and FHWA for workers in the right-of-way?
Answer: ANSI/ISEA Class 2 or Class 3 high-visibility safety vest
FHWA and MUTCD require ANSI/ISEA Class 2 or Class 3 high-visibility apparel for all workers within the highway right-of-way to maximize driver visibility.
What is the primary purpose of a Job Hazard Analysis (JHA) completed before stormwater field inspections?
Answer: To identify and mitigate task-specific hazards before work begins
A JHA systematically identifies hazards associated with each step of a task and establishes controls to eliminate or reduce risks before field work begins.
