Q

the limit current at which the human being can endure the pain of an electric shock ?

A

more than 3mA

35

Device that utilizes a positive means such as lock to hold an energy isolating device in the safe position and prevents energizing of an equipment.

A

Lockout device

44
Q

A warning device, such as tag and a means of a attachment .

A

Tagout device

45
Q

Is an unforseen situation that
threatens your employees, customers, or the public;
disrupts or shuts down your operations; or causes
physical or environmental damage.

A

Workplace emergency

46
Q

Emergencies may be natural or manmade and include
the following:
(3)

A
  1. Natural Disasters
  2. Technological
  3. Human

Q

Identify different emergency scenarios ahead of time and define emergency
procedure/plan for each scenario.

A

Pre-plans

48
Q

Prepare resources in advanced and as a redundancy
(e.g. emergency numbers directory, floor plans, evacuation maps, assembly areas,
emergency supplies, logistics, tools to account people, emergency food and water, etc.).

A

Pre-plans

49
Q

Establish authority during emergencies. Who’s in-charge, who
will do what, define roles and responsibilities.

A

Incident Command Structure

50
Q

Identify training needs, conduct employee trainings and drills in a regular
basis covering all possible scenarios.

A

Employee Training

51
Q

Continuously improve the plan which covers not only the
procedure but covers all resources needed (e.g. equipment, facilities, supplies, etc.) through
regular inspections, audits, drills, post-incident reviews, periodic document review, and
evaluation of the program/system effectiveness.

A

Management System Review

52
Q

refers to medical attention that is administered immediately
after the injury occurs and at the location where it occurred.

A

First aid

53
Q

It often
consists of a one-time, short-term treatment and requires little
technology or training to administer

A

First aid
