What is the OSHA requirement for a safety line used in conjunction with a body harness during aerial tree work?

Which OSHA standard applies to tree workers performing clearing operations near underground utilities?
Answer: 29 CFR 1926.651 (Excavations)
29 CFR 1926.651 covers excavation safety and includes requirements for locating underground utilities before digging.
Under OSHA's heat illness prevention guidance, which factor is NOT considered when assessing heat stress risk?
Answer: Worker's years of experience
Heat stress risk is assessed using environmental factors such as temperature, humidity, and radiant heat—worker experience does not reduce physiological heat load.
OSHA requires that a Job Hazard Analysis (JHA) for tree felling operations must be reviewed and updated when:
Answer: A near-miss or incident occurs, or job conditions change significantly
JHAs must be revisited whenever an incident or near-miss occurs or when site conditions change to ensure controls remain adequate.
