Q

A worker is using a jackhammer to break concrete. For this work:

A

The worker must be provided with safety glasses, safety shoes, a hard hat, and hearing protection.

Using a jackhammer requires several types of personal protective equipment to properly safeguard the employees the physical hazards of the work.

Q

Establishing written standard operating procedures for construction tasks is:

A

Best for high-risk work.

High-risk work is best suited for having written standard operating procedures. Much of the work on a construction is routine, and the good workmanship of the employees can be trusted. For high-risk work and non-routine tasks, job safety analyses and written procedures should be developed to minimize the risk to employees.

Q

Which is a formal deductive risk analysis method?

A

Fault tree analysis

Fault tree analysis is a deductive analysis. A deductive analysis starts with the undesired failure. The analyst then deduces the steps, events, and conditions necessary to obtain the undesired failure. An inductive analysis starts with specific events that may cause problems. The analyst on an inductive analysis (such as failure mode and effects analysis) then infers from the lower-level events the things that could be affected, thus potentially finishing with several undesired failures.

An employee was fatally injured at a jobsite. Once the emergency response is completed, what is the first thing a CHST should do, with respect to investigating the incident?
Isolate the scene and control access to it. Once the emergency response activities are completed, a CHST should isolate the scene and control access to it to prevent additional incidents and to preserve any evidence for the investigation. Reference: Root Cause Analysis Handbook: A Guide to Effective Incident Investigation, Government institutes.
26
What is the most important reason for conducting a thorough incident investigation?
To identify the cause of the incident for implementing corrective actions. Incident investigation is especially important to determine direct causes, uncover contributing incident causes, prevent similar incidents from occurring, document facts, provide information of costs, and to promote safety. Reference: Accident Prevention Manual for Business and Industry, Administration and Programs, 13th Edition, National Safety Council
27
When conducting an interview related to an incident investigation, it is best to interview:
Witnesses individually. When conducting an investigation, the injured parties and witnesses should be interviewed separately.

Reference: Supervisor's Safety Manual, 9th Edition, National Safety Council.
28
What is a root cause of an incident?
Management system deficiency. Causal factors are human errors and equipment failures. When investigating an incident, one should determine why these causal factors were allowed to be present. The answer to these "why" questions are the root causes of the incident. Reference: Root Cause Analysis Handbook: A Guide to Effective Incident Investigation, Government Institutes.
29
A CHST is compiling a summary of injuries and illnesses for presentation to plant management. In the past month, the plant has experienced four federal OSHA-recordable injuries. Two were lost workday cases. Employees in the plant worked 92,350 hours during this period. What is the total OSHA-recordable incidence rate for the month?
8.7 Incidence rates using the method developed by the government are based on the exposure of fill-time workers using 200,000 employee-hours as the equivalent (100 working 40 hours per week for 50 weeks per year). From the problem: Recordable injuries = 4 Employee hours worked = 92,350 Equation: Incidence rate = No. of injuries and illnesses X 200.000 hours Employee hours worked during the period = (4 x 200,000 hours) 92,350 hours = 8.7 Reference: Accident Prevention Manual for Business and Industry: Administration and Program, 13" Edition, National Safety Council.
