Commercial Kitchen Line
Wet floors, fryers, knives and hood fires on a crowded cook line.
Line cooks work fast in a hot, tight space with wet and greasy floors, open flame, hot oil and sharp tools. This guide covers slips, burns, cuts and grease fires, and the floor, equipment and hood maintenance that control them.
The floor is where many kitchen injuries start. Grease, water and dropped food make tile slippery, and cooks move quickly through a tight space carrying hot and sharp items, so a slip can turn into a burn or a cut. Controls start at the source: splash guards, drip trays and drainage, then flooring rated for wet and greasy areas, drainage mats at wet stations, prompt cleanup and slip-resistant footwear.
Heat and steel add the acute injuries. Fryers, flat-tops and salamanders cause contact and splash burns, and knives and slicers cause lacerations. Grease-laden vapor builds up in hoods, ducts and filters and can ignite, so hood cleaning and a working suppression system are core fire controls. The program engineers the floor for traction, arranges equipment to limit reaching over heat, keeps knives sharp and slicers guarded, and maintains the hood and suppression system.
The main hazards and the controls that reduce them
Work down the hierarchy of controls: remove or substitute the hazard where you can, then use engineering and administrative controls. PPE is the last line of defense, not a substitute for the controls above it.
Slips on wet and greasy floors
Grease from fryers and grills, water from dish and prep stations, and dropped food make kitchen floors slippery. A fall is more serious when the worker is carrying hot oil or a knife.
- Contain grease and water at the source with splash guards, drip trays and drainage
- Specify flooring the maker rates for greasy areas, not only a water-wet DCOF result
- Use drainage matting at wet stations and keep it clean
- Clean spills immediately and degrease floors on a set cycle
- Provide slip-resistant footwear rated for oily floors
Burns from fryers, flat-tops, and hot oil
Fryers, flat-tops, salamanders and steam cause contact, splash and steam burns. Water or ice in a fryer makes oil spatter, and moving hot oil risks a large spill.
- Use fryers with built-in filtration or oil caddies so hot oil is not carried
- Arrange equipment to limit reaching over burners and fryers
- Keep water and ice away from fryers and drain wet food before frying
- Keep traffic paths clear where hot pans are handed off
- Train safe handling of hot pans and oil
- Provide heat-resistant gloves and sleeves, and use dry towels
Knife and slicer lacerations
Knives, mandolines, and powered slicers cause cuts during prep and service. Dull knives and rushed handling raise the risk of serious lacerations.
- Keep guards on powered slicers and lock them out for cleaning
- Cut on stable, non-slip boards with proper technique
- Keep knives sharp and store them in racks or sheaths
- Pass knives handle-first and never leave them in a sink of water
- Train safe use of mandolines and slicers
- Provide cut-resistant gloves for slicer cleaning and heavy prep
Grease fire and hood-system ignition
Grease-laden vapor accumulates in the hood and duct system and can ignite into a fast-spreading fire. The hood, duct, and suppression system are the primary defense.
- Maintain the automatic suppression system over cooking equipment
- Have hoods and ducts inspected for grease on the NFPA 96 schedule (quarterly for high-volume cooking such as charbroiling or wok work) and cleaned when contaminated
- Clean hood filters regularly between professional cleanings
- Keep a Class K extinguisher near fryers and griddles
- Train staff to activate the suppression system first, never to use water or move a burning pan, and when to evacuate
The core safety programs for this work
Floor traction and housekeeping
Grease and water are contained at the source, floors are degreased on a set cycle, and spills are cleaned as they happen. Flooring, mats and footwear are chosen for greasy conditions, since a water-only slip rating does not show how a floor performs with grease.
Hood cleaning and fire suppression
Hoods, ducts and filters are inspected and cleaned on the NFPA 96 schedule for the cooking volume, and the suppression system is serviced at least every six months by a qualified technician. Staff know to activate the system first and use the Class K extinguisher as backup.
Knife and slicer safety
Sharp knives, stable boards and set storage reduce cuts. Slicers keep their guards on and are locked out for cleaning, and cut-resistant gloves are worn for slicer cleaning and heavy prep.

Building a Heat Illness Prevention Program That Works
Heat management looks straightforward on paper: monitor conditions, provide water and shade, add breaks, and train workers accordingly. In practice it takes judgment, because conditions shift within a shift and sun, humidity, workload, and PPE all change exposure. A program that holds up puts acclimatization near the top, measures heat the right way, and gives supervisors clear authority to act on defined triggers.
Mental Health Belongs in the Safety Conversation
Most EHS teams manage physical fatigue as a safety risk but treat mental strain as a private matter, though both can affect attention and judgment. WHO estimates depression and anxiety cost 12 billion working days a year globally. Supervisors can notice, ask, listen, and connect, and EHS can check whether workload, staffing, or schedules are adding to it.
Slip, Trip, and Fall Prevention: Simple Steps to Safety
Slips, trips, and falls remain among the most common workplace injuries, yet OSHA's walking-working surfaces standard treats nearly all of them as preventable. Employers must keep floors clean and dry where feasible, guard floor holes and elevated edges, and provide fall protection from 4 feet in general industry, 5 in shipyards, 6 in construction, and 8 in longshoring. Where hazards persist, slip-resistant footwear and clean-up procedures fill the gap.
Fire Safety: Planning and Prevention
Fire safety starts with prevention: OSHA's fire prevention plan targets flammable materials, combustible dust, and ignition sources before they ignite. When prevention fails, an emergency action plan governs evacuation routes, responder roles, and fire extinguishers, alarms, and sprinklers. Regular drills test whether those routes and roles actually hold up under a real evacuation.
OSHA standards shown are federal; states with their own OSHA-approved plans can set different or stricter requirements. Consensus standards and NIOSH guidance are recommendations unless a regulation adopts them. Confirm the rules that apply to your site.
