Food Processing Plant Safety

Food plants mix sharp tools, powerful machines, wet floors, cold rooms and strong cleaning chemicals, often on fast lines and night shifts. Many of the worst injuries happen not during production but during cleaning, when workers reach into machines to sanitize them.

• General Industry
• Food Manufacturing

Machines

• Slicers, grinders, mixers, dicers and conveyors can pull in hands and amputate fingers. Guards must stay in place during production.
• Never reach into a running machine to clear a jam or grab product. See Clearing Jams.
• Know where the emergency stops are on your line. See Emergency Stops.

Sanitation and lockout

Sanitation crews take guards off and put hands and bodies inside equipment, often at night with fewer people around. OSHA has cited many plants after sanitation workers were killed or lost limbs.

• Lock out every energy source before cleaning inside or under a machine, including electric, air, hydraulic and stored energy. Each worker puts on a personal lock. See Lockout/Tagout and Group Lockout.
• Test that the machine won’t start before you reach in.
• Don’t accept “just jog it to clean the belt” without a written procedure that protects you.

Contract sanitation companies must follow the same rules, and the host plant must share its lockout procedures with them.

Knives and cuts

• Keep knives sharp; dull knives slip and strain wrists.
• Wear the cut-resistant or metal mesh gloves your job requires.
• Carry and store knives in scabbards, and never try to catch a falling knife.

Wet floors, cold and heat

• Slip-resistant boots, good drainage and quick cleanup prevent falls. See Slips, Trips & Falls.
• Coolers and freezers need warm layers, warm-up breaks and a way to open doors from the inside. See Cold Storage.
• Cooking, frying and steam areas cause burns and heat stress.

Chemicals

• Sanitizers and cleaners include chlorine, caustic and acid cleaners, and quaternary ammonium. Mixing chlorine with acids or ammonia releases toxic gas. See Corrosives.
• Wear the goggles, face shields, gloves and aprons listed on the safety data sheet, and know where the eyewash is.
• Many plants use ammonia refrigeration. Know the alarm sound and your evacuation route. See Ammonia Refrigeration.

Repetitive motion and dust

• Fast, repeated cutting and packing cause hand, wrist and shoulder injuries. Report early symptoms like numbness or tingling. See Musculoskeletal Disorders.
• Flour, sugar, starch and spice dust can explode. See Combustible Dust.

Young workers

Federal child labor rules bar workers under 18 from running or cleaning many power-driven food machines, including meat slicers and many mixers and grinders. See Young Workers.

Before you clean a machine

• Machine stopped and all energy sources locked out with your own lock
• Stored energy released and start-up tested
• Chemical PPE on, and the right chemical diluted correctly
• Floor drains clear and hoses out of walkways
• Guards put back before the machine runs again
