CPA Sanitation & Disease Prevention 5

Question 1

Under OSHA's Bloodborne Pathogens Standard (29 CFR 1910.1030), what is the first step when a petroleum worker is cut and bleeding on-site?

Accepted Answer

Treat blood as potentially infectious and use gloves before rendering aid

Answer

OSHA's Bloodborne Pathogens Standard requires treating all human blood as potentially infectious and using appropriate PPE such as gloves before contact.

Question 2

In the context of petroleum worksite disease prevention, what does the hierarchy of controls prioritize FIRST?

Accepted Answer

Engineering controls that eliminate or reduce the hazard at the source

Answer

The hierarchy of controls places elimination first, then substitution, then engineering controls — which reduce exposure at the source before relying on PPE or administrative measures.

Question 3

Which disease can be transmitted to petroleum field workers through contact with rodents or their droppings at a field camp?

Accepted Answer

Hantavirus Pulmonary Syndrome

Answer

Hantavirus Pulmonary Syndrome is transmitted by inhaling dust contaminated with infected rodent urine, droppings, or saliva — a real risk in stored-equipment areas.

Question 4

When a petroleum worker must enter a confined space with potential microbial contamination (e.g., tank cleaning), what precaution is SPECIFIC to disease prevention?

Accepted Answer

Use a self-contained breathing apparatus (SCBA) to prevent inhalation of bioaerosols

Answer

SCBA protects workers in confined spaces from inhaling bioaerosols, toxic vapors, and oxygen-deficient atmospheres that may contain pathogenic microorganisms.

Question 5

What is the recommended minimum ratio of toilet facilities to workers at a petroleum construction site per OSHA 1926.51?

Accepted Answer

1 toilet per 10 workers for the first 200 workers

Answer

OSHA 1926.51 requires 1 toilet per 10 workers for the first 200 workers at construction sites, scaling with workforce size to prevent sanitation-related disease.
