Tools or PPE - what should the locker hold?

Start with the intended use. A tool locker with shelves and drawers is very different from a clothing or PPE locker with a hanging rail, shelf and ventilation. Mixing the two costs order and risks moisture damage.

Hand tools, machines and consumables call for shelves and drawers that carry higher point loads. Personal protective equipment such as overalls, safety shoes and a helmet instead needs height, hooks and good air flow so that damp or sweaty clothing can dry out.

Where hazardous substances are handled (oil, solvents, dust), DIN 4547 requires street clothes and work clothes to be stored separately - the so-called black-white principle. Dedicated two-part lockers with a dividing wall handle this.
  • Tool locker: shelves, drawers, perforated panel for tool holders.
  • PPE and clothing locker: hanging rail, hat and shoe shelf, optional mirror.
  • Laundry locker with divider: separate bays for clean and used clothing.
  • Combination locker: shelf on one side, hanging rail on the other.

How many bays and compartments make sense?

Compartment layout follows the number of users and the contents. Common bay widths are 300 and 400 mm, with an overall height of around 1800 mm plus a base or feet. A single 400 mm bay comfortably holds one person's PPE.

Adjustable shelves on a 25 to 30 mm pitch add a lot of flexibility. Watch the shelf load: plain shelves carry roughly 30 to 50 kg, reinforced versions up to 100 kg each. For heavy tools, drawers on telescopic slides pay off because they pull out fully and each carries its own load.

Plan a reserve: a valuables or inner compartment for keys, wallet and phone keeps small items apart and raises acceptance among staff.

Why does ventilation matter so much?

Without air flow, moisture and odour build up inside a closed steel locker. Good PPE lockers therefore have air slots or punched hole rows at the top and bottom of door and body, so a chimney effect draws air upward.

The body is usually made of steel sheet 0.6 to 0.8 mm thick, powder-coated against corrosion. In damp or wet areas such as wash rooms, plastic or stainless-steel lockers are the better choice because they do not rust. A base or feet of about 100 to 150 mm keeps the body off the wet floor and makes cleaning easier.

  • Air slots top and bottom for continuous ventilation.
  • Powder coating for scratch and corrosion protection.
  • Feet or a base against rising floor moisture.
  • Optional sloping top stops dust and items being left on top.
  • For wet areas: plastic or stainless steel instead of painted steel.
Drying lockers are available with heated warm-air versions that dry wet work clothing and shoes before the next shift - useful for field service, construction and fire brigades.

Which locking system suits your operation?

The locking system decides comfort and administrative effort. For fixed assignment a cylinder lock with two keys works well; for changing users a padlock hasp or a keyless combination lock is better.

A master key for management saves forced doors when a key is lost. Electronic locks with an RFID card or transponder remove key management entirely and can be reassigned centrally - the extra cost pays off above all with many users and frequent turnover.

Check whether the locker door needs a view window or name-plate holder. Label frames and viewing windows make assignment within a team easier.

Frequently asked questions

How thick should a steel locker be?

For normal operation 0.6 to 0.8 mm powder-coated steel sheet is enough. For heavily used or public areas, thicker sheet and reinforced doors make sense.

What does the black-white principle in DIN 4547 mean?

When working with hazardous substances, clean street clothing and soiled work clothing must be stored separately. Laundry lockers with a fixed divider and two separate bays achieve this.

Does a tool locker need ventilation?

For pure tool storage, shelf load and stability matter more than ventilation. As soon as damp or sweaty PPE is stored, air slots at top and bottom become essential.

Which lock is best for changing users?

A keyless combination or code lock, or a padlock hasp where each user brings their own padlock. This removes the need for key management.
