Personal protective equipment, commonly referred to as PPE, is equipment worn to minimize exposure to hazards that cause serious workplace injuries and illnesses. These injuries and illnesses may result from contact with chemical, radiological, physical, electrical, mechanical, or other workplace hazards. PPE is designed to protect many parts of the body, including: head, eyes, face, respiratory system, torso, arms, hands, legs, feet, and hearing.
Importance of PPE
Personal protective equipment is important because it acts as the last line of defense against workplace hazards. Certain occupations are inherently hazardous, such as working in construction, firefighting, mining and healthcare. Workers in these occupations come in direct contact with workplace hazards. PPE safeguards workers from hazards they cannot eliminate through engineering controls, work practices and administrative controls. It helps to prevent workplace injuries and fatalities. According to statistics from the Bureau of Labor Statistics, appropriate use of PPE can reduce the number of injuries and illnesses on the job significantly.
Common Types of PPE
Some common types of PPE and their purposes are discussed below:
Head Protection
Hard hats are designed to protect the head from impact and penetration from falling and flying objects on construction sites, shipyards, and other industrial work environments.
Eye and Face Protection
Safety goggles, safety glasses, face shields and welding helmets protect workers’ eyes, face, and head from hazards like flying particles, metal sparks, chemical splashes, and ultraviolet radiation.
Hearing Protection
Earplugs, earmuffs and noise attenuating devices are designed to reduce noise exposure which can lead to permanent hearing loss. They are especially important in transportation, mining, construction and manufacturing industries.
Foot Protection
Safety shoes and boots with impact protection and electrical hazards protection are important PPE for construction, manufacturing, warehousing and farming jobs where there is a risk of heavy falling objects or exposure to sharp objects that can cause injury.
Hand Protection
Gloves made of different materials like leather, rubber, and Kevlar protect hands from burns, cuts, chemicals, vibration and extreme temperatures. Welding gloves, cut-resistant gloves and chemical resistant gloves examples of specialized hand protection.
Body Protection
Body protection includes protective coveralls, aprons, vests and full body suits used in situations requiring protection from chemical, radiological, biological and physical hazards. Firefighter’s gear, riot gear and hazmat suits provide protection from heat and flames, ballistic threats and toxic environments respectively.
Respiratory Protection
Masks, respirators and breathing apparatus remove toxic gases, vapors, mists, fumes, dusts and aerosols from the air we breathe. Different respiratory protective equipment is used for particulate masks, supplied airline respirators, self-contained breathing apparatus and Escape type respirators.
Importance of Training
Training is an important component of any PPE program. Workers should receive initial and annual refresher training on PPE selection, limitations, proper use, care and storage before being assigned work requiring protective equipment. Training helps them understand workplace hazards and the role and proper use of PPE in protecting against those hazards. It also involves hands-on practice and feedback on correctfitting techniques. Supervisors play a key role in ensuring workers wear PPE properly. Training and enforcement help achieve the maximum protective benefits of PPE.
Selection Criteria
Many factors need to be considered while selecting appropriate PPE for a job. These include:
– Hazard assessment of the workplace to identity potential physical, chemical and other hazards.
– Understanding the type, level and route of exposure like inhalation, absorption, ingestion or skin/eye contact.
– Compatibility with other simultaneously used PPE like clothing, equipment and respirators.
– Fit needs- one size may not fit all. Adjustable features and multiple sizes often required.
– Durability and resistance to wear and tear from the type of work activity.
– Comfort and weight for effective use over complete work shifts.
– Maintenance and replacement schedules as per manufacturers’ guidelines.
Regulatory Compliance
Most countries have well-defined regulations regarding the selection, use and maintenance of PPE in workplaces. In the United States, the Occupational Safety and Health Administration (OSHA) enforces requirements pertaining to PPE under the Personal Protective Equipment Standard in Part 29 CFR 1910.132 of General Industry Regulations. Employers are required to assess workplace hazards, select PPE appropriate to those hazards and ensure its proper fitting and care. OSHA also conducts inspections of worksites and can issue citations and penalties for regulatory non-compliance around PPE use. Overall, regulations aim to reduce risk of injury or illness through enforced safe PPE practices.
In summary, PPE plays a vital role in promoting safety and health at work. With proper training, selection and use as per regulations, PPE can significantly reduce the incidence and severity of workplace injuries, illnesses and fatalities across high-risk industries and occupations. An effective PPE program makes the workplace safer for all while also meeting compliance requirements.
