CHST EXAM ACTUAL TEST PAPER 2025/2026 QUESTIONS
WITH ANSWERS GRADED A+
✔✔The work cycle should be shortened for any worker whose oral temperature
exceeds ? degrees Centigrade or ? Fahrenheit degrees. - ✔✔37.6 C or 99.68 F
✔✔Body water weight loss should not be more than ? percent of total body weight per
day. Fluid intake should be increased if loss approaches that amount. - ✔✔1.5 percent
Body water loss measurements are taken by weighing the worker at the beginning and
end of each day.
✔✔FMEA can provide mathematical predictions about the - ✔✔expected rate of failure
for the process.
✔✔Exit discharge refers to an exit which leads - ✔✔directly to an outdoor area or street
✔✔Exit routes are different from exit discharges in that they - ✔✔do not necessarily
pass out into a street, yard, or open area away from the building.
✔✔An exit route is an - ✔✔unobstructed walking traffic pattern which leads to any place
of relative safety. An exit route, for example, commonly leads to a refuge area.
✔✔Refuge areas are - ✔✔places along an exit route which have fire resistant
protections which will retard the advance of flames and smoke.
✔✔In order to meet the conditions of being classified as a chemical accident or release,
the occurrence must meet one or more of the following criteria: - ✔✔A chemical
accident or release must result in one or more human fatalities.
A chemical accident or release must result in the hospitalization of three or more
workers or non-employees in the vicinity.
A chemical accident or release is such that it causes an estimated half million dollars in
property damage. Such damage can occur at the construction site or offsite.
A chemical accident or release causes evacuation, environmental contamination, or
closure of transportation routes.
✔✔Emergencies involves - ✔✔Release of toxic substances in high concentrations.
Imminent danger to life and health (IDLH). Oxygen deficient environments where
employees could suffocate or sustain damage to respiratory systems.
Clear danger of fire and explosion.
Most emergency situations require evacuation of an area because of the danger posed
to employees.
, ✔✔An incident command system is - ✔✔directed by a Unified Command which
develops and implements overall strategies involving fire departments, police, hazmat
teams, or other agencies.
✔✔A HAZMAT team is - ✔✔an organized group of workers designated to handle and
control leaks or spills of hazardous materials.
✔✔Before marching into a site where hazards may be yet unknown, the HAZMAT team
surveys and monitors the site by: - ✔✔Assessing the level of threat for IDLH (Immediate
Danger to Life and Health) or ionizing radiation.
Monitoring for ionizing radiation with test equipment which measures such radiation.
Employ gas meters and detector tubes to measure conditions which may cause death
or serious harm. Content levels of oxygen are frequently measured in earth cavities
which result from cave-in, for example. Ground samples or plugs may be taken for
laboratory assessment of toxicity.
✔✔An investigation team must be set up and appear on site within a ? hour period from
the time of the accident. - ✔✔48 hrs
✔✔The report of the investigation must be retained for ? - ✔✔5 years
✔✔Determining the ? is a primary goal of both EPA and OSHAs agency investigative
teams. - ✔✔root cause
✔✔OSHA headquarters and EPA's teams are directed by their own headquarters.
However, the results must be - ✔✔Combined in a public report
✔✔All accidents, incidents, and "near-miss" occurrences at work sites should be -
✔✔investigated even if they result in property damage only or have no visible damage
whatsoever.
✔✔OSHA accident incident rate of injury - ✔✔Injuries divided by hours worked times
200 000
✔✔On form 300A The sum total of columns ?, ?, and ? can be added to obtain the total
number of recordable non-fatal injuries and illnesses. - ✔✔H, I , J
✔✔OSHA Form 300 -A sum of all Form 300s can be manually counted and added
according to category. To find - ✔✔total number of nonfatal injuries and illnesses at a
work site.
✔✔A catastrophic accident involving hospitalization, amputation, or loss of an eye must
be reported within ?hours. - ✔✔24hrs by phone or on hot line
