Safety training every new brewery worker needs on day one
A brewery looks calm until you know where the hazards are. Carbon dioxide, hot liquid, caustic cleaners, pressure vessels and wet floors can all hurt someone in their first week. A short, practical induction before any work starts is the cheapest safety measure you will ever buy.
Do it before the first task, not after
The worst time for safety training is "when we get a chance". New starters are at their most at risk in the first days, when they do not know the building, the kit or the warning signs. Make safety induction the first thing a new person does, before they touch a hose or move a keg.
Keep it to about two hours, mostly on the floor rather than in a meeting room. Walk the building. Point to the hazards. Show the emergency stops, the eye wash station, the fire extinguishers and the exits. Then ask the new starter to show you.
Carbon dioxide: the invisible hazard
Fermentation produces large amounts of carbon dioxide. It is colourless, has no reliable smell at dangerous levels and is heavier than air, so it collects in low places: cold rooms, cellars, pits and the bottom of tanks. Workplace exposure limits are around 0.5% averaged over a shift. At a few percent people get headaches and breathlessness. At around 10% people can lose consciousness quickly.
Teach three rules. If you feel dizzy, breathless or get a sudden headache in an enclosed space, leave first and report after. Never go back in to rescue a collapsed colleague without help, because the rescuer is often the second casualty. Report hissing fittings and open tanks at once. A fixed CO2 monitor in the cold room is a sensible investment.
Hot liquids and steam
Brew days involve wort near 100 °C, hot liquor at 75 to 80 °C and steam from kettles and cleaning. Burns come from splashes, hoses that whip loose and valves opened in the wrong order. New staff should never open a valve on the hot side until they have been trained on that specific line.
Show them how hoses are secured, where hot surfaces are and what first aid to give: cool running water on a burn for at least 20 minutes, then medical help for anything larger than a small patch.
Caustic and acid cleaners
Brewery cleaning uses caustic soda solutions, often around 2% at 70 to 80 °C, plus acid cleaners and sanitisers. Caustic causes serious burns and can blind someone with a single splash. Every new starter should know where the safety data sheets are kept, how chemicals are stored and labelled and never to mix chemicals.
Goggles and chemical gloves are mandatory for anyone handling cleaners, every time. Show the eye wash station and how to use it: hold the eye open under running water for at least 15 minutes and get medical help.
Pressure, tanks and confined spaces
Fermenters and serving tanks hold beer under pressure. Opening a manway or fitting on a pressurised tank can cause serious injury. Teach new staff never to open any tank fitting without checking the pressure gauge reads zero and the tank is vented. Even then, only once they have been trained on that tank.
Tanks are also confined spaces. Nobody enters a tank, for any reason, without a formal confined space procedure, gas testing and a second person outside. Most brewery tanks can be cleaned without anyone going inside. Make that the rule.
Lifting, slips and the everyday hazards
Many injuries in breweries are ordinary ones. A full 50 litre steel keg weighs over 60 kg. Malt usually arrives in 25 kg bags. Teach safe lifting, use trolleys and keg lifters and never ask one person to lift a full keg alone. Wet floors are constant, so good boots with slip-resistant soles are part of the uniform, not an option.
Grain dust from milling can irritate lungs and, in enclosed spaces, burn. Keep the mill area clean and show staff the dust extraction or masks you use.
Fire, electrics and first aid
Show every new starter the fire exits, the assembly point and the extinguishers. Explain which type goes with which fire. Brewhouses often run gas burners or steam boilers, along with heavy electrical loads on pumps, chillers and heating elements. Wet floors and electricity are a dangerous pair, so teach staff to report damaged cables, wet sockets and tripped breakers rather than resetting them themselves.
Point out the first aid kit and name the trained first aider on each shift. Write the nearest hospital and emergency numbers on a sign by the phone. In an emergency, nobody should be searching for an address.
Sign it off and repeat it
End the induction with a short checklist that both the trainer and the new starter sign. Keep it on file. Repeat key safety points at monthly team meetings and after any near miss. Our guide to brewery safety culture covers how to keep safety alive after day one.
Safety training is one part of the wider systems a brewery needs: inductions, rosters, records and accountability that work even when the founder is away. Building those systems properly takes more than a checklist, which is where structured training helps.
Your first step: walk your brewery today and list every hazard a new starter would not recognise. That list is your induction.
Common questions
Why is carbon dioxide dangerous in a brewery?
CO2 from fermentation is invisible and heavier than air, so it collects in cold rooms, cellars and tanks. High concentrations cause dizziness and can cause unconsciousness.
What protective equipment do new brewery workers need?
At minimum, safety goggles, chemical resistant gloves and slip-resistant safety boots, plus training on when to use each.
Should anyone ever enter a brewery tank?
Only under a formal confined space procedure with gas testing and a second person outside. Most tanks can be cleaned without anyone going in.
