Personal protective equipment can help keep you safe.

What is personal protective equipment (PPE) and why is it important? According to 85% of electrical workers who participated in a recent Fluke survey, not very. They said they skip wearing proper protective gear because it’s inconvenient. Yet, we know that this protection gear is really your last line of defense to remain safe in an arc flash or arc blast environment. Of course, the best way to avoid shock or electrocution is to stay far away from living components and to only work on dead equipment. Unfortunately, even when taking the appropriate precautions, arc flash and other accidents can still happen. That’s why electrical PPE is your last line of defense to remain safe in an arc flash or arc blast.

The United States Department of Labor’s Occupational Safety and Health Administration (OSHA) and NFPA create robust guidelines and regulations around job site safety. NFPA 70E, the Standard for Electrical Safety in the Workplace, details the requirements and the PPE required for safe work practices. While NFPA 70E standards are not required by law, they were written to help meet the requirements that OSHA does require by law. In order to figure out what PPE is necessary for certain environments; you need to start by conducting a hazard assessment.

What are PPE requirements?

PPE’s are the ideal wear for any job site, especially hazardous ones. Taking a hazard assessment tells you what PPE is required on site. Also, is also the first step toward developing a safety program. It should serve as your foundation for creating a safe work environment. You need to identify the potential hazards in the workplace, both physical and health-related.

Potential health hazards are things like exposure to harmful dust, chemicals, or radiation. Physical hazards can include a broad variety of work areas including, but not limited to:

• Moving objects
• Sharp edges
• Potential for falling objects
• Electrical connections
• Extreme temperatures

As you conduct a walkthrough of the job site, you’ll want to document every possible hazard. The information can be organized later, and the proper PPE is determined to protect employees from each hazard. The job site should also be periodically reassessed to ensure any changes are considered, and the PPE levels set are enough.

Selecting proper PPE

Here are some things to keep in mind after taking the hazard assessment. Firstly, try and remove any hazards you come across to. Keep a hierarchy of control’s in mind as you set up your plan. The National Institute for Occupational Safety and Health (NIOSH) ordered these controls in order from what is most effective to what is least effective in protecting workers’ safety.

1. Eliminate the hazard
2. Substitute less hazardous equipment or materials
3. Engineer controls to reduce exposure or severity
4. Warning, signs, and other communications
5. Administrative controls; including safe work practices
6. Personal protective equipment

If you’ve gone through the hierarchy and come to PPE as the final step, come up with a list of PPE for electrical work. You should follow NFPA 70E guidelines to select the minimum PPE standards for areas you noted in the assessment. Table 130.5(C), or the Table Method of NFPA 70E helps to estimate the likelihood of an occurrence of an arc flash incident in different AC and DC systems and whether PPE should be required.

The table is a minimum required level. It is always a good idea to not just meet the minimum safety requirements, but to exceed standards. OSHA requires many of the PPE categories to meet standards developed by the American National Standards Institute (ANSI) for these three types of PPE:

• Eye and face protection,
• Head protection and
• Foot protection.

ANSI doesn’t have a standard for gloves, but OSHA recommended the selection be based upon the tasks being performed.

PPE training

As part of OSHA’s standards, employers are required to train employees who need to wear electrical PPE. Their training scope is about what to wear, when, how, proper maintenance, and how to dispose of it. The training also covers the PPE’s limitations.

Understanding the limitations of PPE is an important aspect of the training so one should take it seriously. Ultimately, wearing the proper protective clothing is viewed as the first line of defense in case of arc flash. But remember, PPE is not foolproof. Nevertheless, when combined with good safety practices, PPE provides the best possible outcome in the event of an arc flash or arc blast.

Including PPE training as part of your regular safety training can also help keep all employees up to date on any changes and give you a chance to review the effectiveness of your electrical PPE measures. That safety training should make sure everyone is taking the appropriate steps to prevent arc flash incidents and minimize their occurrences. Wearing and using proper PPE needs to be one of those steps. It will reduce your injuries and could save your life.
