Food Industry PPE: Using Safety Gear to Reduce Injuries, Contamination Risk

This page was updated March 8, 2023

In all likelihood, if you don’t work in the food manufacturing industry, you might not immediately think of chemical exposure as a major hazard.

“From anhydrous ammonia used in cooling systems to disinfectants used to clean equipment, there are many hazardous chemicals found in food plants,” according to a Food Industry Executive article. “Workers who may come into contact with these chemicals must be informed, use proper work practices and wear appropriate personal protective equipment.”

In fact, it’s enough of a risk that citations involving the safe management of highly hazardous chemicals (CFR 1910.119) ranked No. 8 on the Occupational Safety and Health Administration’s Top 10 violations list for the food manufacturing industry in 2019—and third (at more than $730,000) in total fines.

What’s more, OSHA citations for improper PPE use (CFR 1910.132) ranked No. 10 and accounted for another $103,000 in fines.

Why Is PPE Selection So Tough in the Food Industry?

In food manufacturing, PPE must play a unique balancing act. Not only must manufacturers protect their workers, they must also protect the food. Protective clothing and its use are critical factors in both reducing harm to the worker and contamination of the food product.

“Protective clothing can become a risk to your food product through both microbiological contamination and physical contamination,” an HACCP Mentor post notes. “Because of this, your risk assessment (or hazard analysis) should document associated hazards at each step in your process where this type of clothing may come into contact with food product.”

Food manufacturing workers use a wide array of protective clothing, including suits, overalls, smocks, jackets, aprons, sleeves and hair covers. Gloves—both those resistant to cuts and chemicals and disposable varieties—are also critical. And if there’s potential for exposure to toxic fumes, respirators may also be required.

Specific materials can be critical for PPE used in food processing and manufacturing. DuPont, for instance, recommends protective clothing made from its Tyvek fabric. The materials “are designed to help prevent contamination from dust particles, bacteria, spores and parasites carried on regular clothing or the human body,” according to the company.

Both employers and PPE producers are working to increase best practices among wearers by making safety gear more comfortable. When it’s uncomfortable, workers may take it off when they shouldn’t or become distracted from their jobs, which can affect performance.

DuPont’s Tyvek suit, for instance, is designed to be breathable, for comfort, as well as to provide a protective barrier from particles, says Dan Bowen, northeast regional sales manager for DuPont’s Personal Protection group. (Better MRO talked with Bowen at 2019’s ASSP Safety show.)

Fit is equally important for safety, says safety consultant Abby Ferri.

“PPE needs to conform to each employee’s body dimensions to be effective; otherwise, it can be a safety hazard itself,” she explains in an article in Refrigerated & Frozen Foods magazine. “PPE that’s too loose can get caught in machinery and cause injury, while PPE that’s too tight can be uncomfortable, which discourages its use. Employers must make every effort to purchase the sizes needed.” 

Curbing Food Contamination Risk with PPE

To identify areas where food production facilities should consider contamination risk related to PPE, conducting regular hazard analyses is critical.

The HACCP Mentor post identifies seven items across three contamination categories that safety teams should consider when conducting hazard analyses.

Potential physical contamination risks:

·       Damaged or torn plastic gloves.

·       Loose threads falling from clothing or aprons.

·       Head coverings not effectively restraining hair.

Potential microbiological contamination risks:

·       Gloves not changed between raw and ready-to-eat foods.

·       Boots not cleaned between low-risk and high-risk production areas.

·       Overalls not removed prior to visiting restrooms.

Potential metal contamination risks:

·       Damaged metal mesh gloves.
