Experience the Quality With Free CHST Exam Questions That Helps Candidates Pass

Improper setup on slopes destabilizes cranes, creating tip-over risks that can be catastrophic. Controls include level ground, cribbing, outrigger pads, and soil assessments. Operator fatigue, noise, and leaks are hazards but less severe. OSHA requires cranes to be set on firm, level surfaces. Recognizing and correcting setup issues reflects CHST’s hazard identification priority: addressing catastrophic risks first with engineering and administrative controls.

Electrocution is a leading cause of crane fatalities. OSHA requires maintaining minimum clearance distances (usually 10 ft, greater for higher voltages) or contacting the utility for de-energization/insulation. Gloves or signs are inadequate; operator skill alone is not reliable. Planning must include site surveys, markings, and spotters. Documented coordination with utilities ensures compliance and safety. This control addresses the hazard at its source, reflecting CHST focus on preventing catastrophic incidents with engineering and administrative measures.

Normal oxygen concentration is 20.9%. Readings below 19.5% are oxygen-deficient and dangerous. At 15%, workers are at risk of impaired judgment, unconsciousness, and death. The correct step is to ventilate until safe levels are restored. PPE such as SCBA may protect individuals but does not address the hazard for all and complicates rescue. Short-duration entry is still unsafe. Extra attendants do not mitigate the deficiency. OSHA confined space standards require testing, ventilation, continuous monitoring, and entry permits. This control reflects CHST priorities: eliminate atmospheric hazards before exposure and verify safe entry conditions.

Mold releases spores that cause respiratory irritation, asthma, or infections. Workers must be protected with engineering controls (containment, ventilation) and PPE (respirators, disposable clothing). Cosmetic concerns, fatigue, and dust are secondary. OSHA and EPA guidelines emphasize hazard recognition and exposure prevention. CHST professionals must identify biological hazards and implement controls before demolition.

Ignoring barricades signals cultural and enforcement gaps. Leaders must explain barricade purposes and enforce compliance with progressive discipline. Removing or weakening controls invites incidents. CHST professionals must ensure leaders communicate expectations, explain hazard rationales, and apply enforcement consistently to sustain compliance and safety culture.
