3 5/3/2015Industrial Safety Lecture Two2 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.

4 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 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. variety of devices and garments such as goggles, coveralls, gloves, vests, earplugs, and respirators. 5/3/2015Industrial Safety Lecture Two 3

5 Employer’s Responsibilities (OSHA Subpart I:1910.132-140) What Kind of PPE Approved PPE Maintained PPE Training to use PPE What Kind of PPE Approved PPE Maintained PPE Training to use PPE 5/3/2015Industrial Safety Lecture Two4 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.

6 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

7 New Employee Orientation 5/3/2015Industrial Safety Lecture Two6

8 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. 5/3/2015Industrial Safety Lecture Two7 1910.132(f) Training

9 5/3/2015Industrial Safety Lecture Two8 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.

10 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
