OSHA 15-Hr Disaster Site Worker study guide
OSHA 15-Hr Disaster Site Worker · Work through your exam, one topic at a time.
The OSHA 15-Hr Disaster Site Worker course is a short awareness-level safety course aimed at people who work at disaster sites: debris removal crews, utility and cleanup contractors, volunteers, and support staff who enter damaged areas after hurricanes, floods, tornadoes, earthquakes, or man-made incidents. The course builds awareness of the conditions that make disaster sites different from ordinary construction sites - unstable debris, contaminated floodwater, downed power lines, confined spaces, heat stress, and mixed chemical exposures - and gives workers a common vocabulary for hazard recognition, personal protective equipment selection, respiratory protection and air monitoring basics, hazard communication, and site control and decontamination practices. The OSHA 15-Hr Disaster Site Worker study guide has 5 sections and about 2,039 words.
01Disaster Site Hazards and Worker Safety Awareness
This domain tests whether you understand that a disaster site is a fundamentally different workplace from a construction site - unstable, uncontrolled, and shared with many agencies - and whether you can name hazards, cite the controlling requirement, and slot into the command structure without becoming a second casualty. An incident command system (ICS) under unified command runs the site.
423 words, about 2 min02Personal Protective Equipment for Disaster Sites
This domain tests whether you can select and wear PPE from the hazard assessment rather than from habit, and whether you understand that every added layer of protection costs mobility, communication, and heat tolerance. The employer assesses the workplace, selects the equipment, communicates the selection decision, provides it at no cost, and trains workers on when and why it is needed and how to don, doff, adjust, and care for it.
413 words, about 2 min03Respiratory Protection and Air Monitoring
This domain tests the administrative scaffolding around the respirator - medical clearance, fit testing, seal checks, cartridge schedules - plus the monitoring that decides whether a respirator belongs on the face at all. A written program, a medical evaluation by a physician or other licensed health care provider before fit testing or use, annual fit testing for each make, model, and size, a user seal check at every donning, training, a cartridge change schedule, cleaning and storage, and replacement of worn parts.
389 words, about 2 min04Hazard Communication and Chemical Exposure
This domain tests whether you can get usable chemical information on a site where most of the chemicals were never labeled for you, and whether you can turn a monitoring number into an exposure decision. 1910.1200 requires a written hazard communication program, containers labeled with GHS pictograms and signal words, accessible safety data sheets, and training before exposure.
392 words, about 2 min05Site Control, Decontamination, and Safe Work Practices
This domain tests whether you can keep a hazard from following a worker off the site - through zone control, a disciplined decontamination line, and the everyday work practices that prevent the quiet injuries. The exclusion zone is where contamination exists; only trained, PPE-equipped, logged-in workers enter it.
