committing an unsafe...
Working condition - Answers An employer failing to provide proper PPE creates an unsafe...
ANSI Z133 - Answers For arborcultural operations, what is the standard that employers must follow
when implementing a structural safety program?
Job briefings - Answers What documents are used to formally review site conditions and job
procedures.
Stop, think, act, review - Answers What does the acronym S.T.A.R represent in arborcultural
operations?
Behavior based - Answers Herbert Heinrich instituted study on industrial accidents in the workplace
that resulted in finding what principles were the cause of the accidents?
Leading indicators - Answers Unsafe acts, close calls at the bottom of the accident prevention
pyramid are called
Lagging indicators - Answers Serious injuries or fatalities in the workplace are known as
Multiple causation theory - Answers Petersen (2001) states that a number of contributing factors and
causes that randomly interact are responsible for injuries in the workplace, and this theory is called?
