Personal Protective
Equipment and Tool
Safety

Introduction to PPE
Employees must be protected from harm.
Common methods for doing this are
Engineering Controls, Work Practices,
Administrative Controls and, Personal
Protective Equipment (PPE). Sometimes
one or more of the above is used and at
times all are used to provide adequate
protection. When only PPE is used, the
PPE is the only thing protecting the
employee from the danger. This unit
discusses basic types of PPE and the
employer requirements.

What is personal protective
equipment?
 Personal protective equipment, or PPE, is
designed to protect employees from serious
workplace injuries or illnesses resulting from
contact with chemical, radiological, physical,
electrical, mechanical, or other workplace hazards.
Besides face shields, safety glasses, hard hats, and
safety shoes, PPE includes a
variety of devices and garments such as goggles,
coveralls, gloves, vests, earplugs, and respirators.

Employer’s Responsibilities
(OSHA Subpart I:1910.132-140)
What Kind of PPE Approved PPE
Maintained PPE Training to use PPE
OSHA’s primary PPE standards are in Title 29 of the Code of Federal
Regulations (CFR), Part 1910 Subpart I, and equivalent regulations in states
with OSHA-approved state plans, but you can find PPE requirements
elsewhere in the General Industry Standards. For example, 29 CFR 1910.156,
OSHA’s Fire Brigades Standard, has requirements for firefighting gear. In
addition, 29 CFR 1926.95-106 covers the construction industry. OSHA’s
general PPE requirements mandate that employers conduct a hazard
assessment of their workplaces to determine what hazards are present that
require the use of PPE, provide workers with appropriate PPE, and require
them to use and maintain it in sanitary and reliable condition. As an employer,
you must assess your workplace to determine if hazards are present
that require the use of PPE.

1910.132(d) Hazard Assessment
 (2)The employer shall verify that the required workplace
hazard assessment has been performed through a written
certification that identifies:
 The workplace evaluated;
 The person certifying that the evaluation has been
performed;
 The date(s) of the hazard assessment; and,
 Which identifies the document as a certification of hazard
assessment

New Employee Orientation

Employer’s Responsibilities
 If such hazards are present, you must select PPE and require employees to
use it, communicate your PPE selection decisions to your employees, and
select PPE that properly fits your workers. You must also train employees
who are required to wear PPE on how do the following:
 Use PPE properly,
 Be aware of when PPE is necessary,
 Know what kind of PPE is necessary,
 Understand the limitations of PPE in
 protecting employees from injury,
 Don, adjust, wear, and care for PPE, and
 Maintain PPE properly.
1910.132(f) Training

Employee’s Responsibilities
 Inspect Maintain Report Defects
Employees should look at their equipment on a daily basis to
make sure it is good working order. This is the responsibility of
each employee.
PPE, especially eye wear and face masks, should be cleaned
daily by the person who wears it.
The employee must reports any problems with PPE, as well as
other protective equipment, as soon as it is detected.

1910.132(f) Training
 (2)Workers must demonstrate an
understanding of the training and the ability to
use PPE properly, before being allowed to
perform work requiring the use of PPE:
 (4)Verify that each employee has received and
understood the required training through a written
certification that contains:
 The name of each employee trained,
 The date(s) of training, and that
 Identifies the subject of the certification

1910.138(a) General requirements
 Employers shall select and require employees
to use appropriate hand protection when
employees' hands are exposed to hazards such
as those from:
 Skin absorption of harmful substances;
 Severe cuts or lacerations;
 Severe abrasions;
 Punctures;
 Chemical burns;
 Thermal burns; and
 Harmful temperature extremes
