BAT Safety Procedures & PPE 2 — Questions and Answers
Question 1: When working in a confined space near a backflow preventer, what is the FIRST action a tester must take before entry?
- Begin testing immediately to save time
- Conduct atmospheric testing for oxygen and hazardous gases (Correct answer)
- Put on a hard hat and enter
- Call the water utility for permission
Correct answer: Conduct atmospheric testing for oxygen and hazardous gases
Confined spaces must be tested for oxygen levels and hazardous gases before entry to prevent asphyxiation or explosion.
Question 2: Which type of glove material is MOST appropriate when handling backflow assemblies that may be exposed to chemical backflow contaminants?
- Cotton work gloves
- Leather gloves
- Nitrile or chemical-resistant gloves (Correct answer)
- Latex surgical gloves
Correct answer: Nitrile or chemical-resistant gloves
Nitrile or chemical-resistant gloves provide protection against chemical exposure that cotton, leather, or standard latex gloves cannot offer.
Question 3: A backflow assembly tester notices water is spraying from a fitting during a test. What is the correct immediate response?
- Continue the test and note the leak on the report
- Step away and shut off the upstream isolation valve (Correct answer)
- Place a bucket under the spray and proceed
- Call the customer and wait for instructions
Correct answer: Step away and shut off the upstream isolation valve
An uncontrolled water spray creates a slip hazard and potential injury risk, requiring immediate shutdown of the upstream supply.
Question 4: What minimum safety footwear is recommended for a backflow tester working in a meter vault or pit?
- Standard athletic shoes
- Steel-toed, slip-resistant boots (Correct answer)
- Rubber flip-flops
- Open-toed sandals with non-slip soles
Correct answer: Steel-toed, slip-resistant boots
Steel-toed, slip-resistant boots protect against falling tools, heavy assemblies, and wet/slippery vault surfaces.
Question 5: Which OSHA standard primarily governs confined space entry procedures for backflow testers working in underground vaults?
- 29 CFR 1926.502
- 29 CFR 1910.146 (Correct answer)
- 29 CFR 1910.132
- 29 CFR 1926.651
Correct answer: 29 CFR 1910.146
29 CFR 1910.146 covers permit-required confined spaces and specifies entry procedures, atmospheric testing, and attendant requirements.
Question 6: When using a differential pressure gauge kit during a backflow test, what PPE is essential to protect against sudden pressure release?
- Ear protection only
- Safety glasses or goggles (Correct answer)
- Hard hat only
- High-visibility vest
Correct answer: Safety glasses or goggles
Safety glasses or goggles protect the eyes from water spray or debris that can be ejected during sudden pressure release from test fittings.
Question 7: A tester is working near a roadway to test a backflow assembly on a public main. What safety measure is REQUIRED before beginning work?
- Post a sign 50 feet away and proceed
- Set up proper traffic control with cones, barriers, and signage per local regulations (Correct answer)
- Work quickly to minimize exposure to traffic
- Ask a passerby to watch for traffic
Correct answer: Set up proper traffic control with cones, barriers, and signage per local regulations
Work zones near roadways require proper traffic control devices and signage to protect workers and the public per MUTCD guidelines.
