Safety — California C-10 Practice Questions

32 questions · 14% of the Law & Business exam

Worked questions

1. A worker must enter equipment believed de-energized. What confirms the safe condition?

Isolation, energy control, and verified absence of voltage
BA verbal promise from another trade
CA dark pilot light
DA stopped motor only

Why A is correct

Control indications can fail and alternate sources can backfeed. A complete energy-control and verification process protects against unexpected energization.

2. How should required personal protective equipment be selected?

AAfter an injury occurs
BBy worker clothing size alone
CBy lowest price only
From documented hazards, fit, and applicable standards

Why D is correct

PPE must protect against identified task hazards without creating incompatible risks. Selection also requires training, inspection, maintenance, and enforcement.

3. What is the purpose of an Injury and Illness Prevention Program?

ATransfer all safety duty to employees
BReplace every specific safety order
A documented hazard-control system
DAddress accidents only after they occur

Why C is correct

An effective IIPP is an active management system for responsibility, communication, assessment, correction, training, records, and investigation. A paper plan alone is insufficient.

4. A new outdoor crew begins strenuous work during a heat wave. Which complete set of controls belongs in the plan?

AWaiting for a collapse before action
BOnly sunscreen
CLess water to reduce breaks
Water, shade, training, and response

Why D is correct

The best answer is: Water, shade, training, and response. Heat illness can escalate quickly and new or returning workers may be especially vulnerable. California requirements call for preventive systems rather than response after symptoms become severe. The new fact pattern changes the setting, not the governing rule or management control. The other choices either skip a required step, apply a different rule, or fail to address the stated risk.

A disconnect is open, but a worker does not lock out sources or test for voltage before touching conductors. What establishes a safe de-energized condition?

A superintendent sees an employee working beside an unprotected opening that presents imminent fall exposure. What is the first response?
After heavy rain, an excavation resumes without a competent person examining soil, water, access, and protective systems. What safety step was required?
An employee suffers a qualifying serious injury at a jobsite. Beyond emergency care, what employer actions are required?
During high-heat work, an employee becomes confused and collapses. What action takes priority over routine cooling breaks?

On a multiemployer site, a general contractor knows about an exposed opening but assumes only the affected subcontractor has duties. Is that assumption sound?
The company buys identical gloves and eye protection for every task without assessing exposure or fit. How should PPE be selected?
