Laboratory safety signage: how can risks and instructions be made immediately visible?

In a laboratory, safety signage channels workflows, prevents hazards and steers safe practice. Pictograms compliant with ISO 7010, chemical CLP/GHS labelling, floor marking and anti-slip tapes, lockout/tagout (LOTO) devices, inspection labels… A complementary toolkit that makes information visible, durable and unambiguous, from the receiving airlock to cleanrooms. Lab-ready materials (vinyl, PVC, aluminium, photoluminescent), high-performance adhesives and crisp legibility make the difference day in, day out.

What are the different types of laboratory safety signage?

Safety signage comprises several complementary categories.

• Safety pictograms: standardised shapes and colours (to ISO 7010 and ISO 3864) for prohibition, mandatory action, warning and emergency/escape. For chemicals, CLP/GHS labelling (red diamond pictograms) is required. Media: self-adhesive vinyl, rigid PVC, aluminium, photoluminescent versions for evacuation in case of lighting failure.

• Floor marking: high-durability vinyl/PP tapes, paints and anti-slip strips to demarcate areas, traffic flow, storage zones and escape routes. Resistant to abrasion, cleaning agents and common laboratory products; quick, neat installation (5S method).

• Lockout/Tagout (LOTO): padlocks, breaker lockouts, multi-lock hasps and lockout tags prevent any re-energisation during intervention. Clear, durable marking strengthens procedure and traceability.

• Inspection/date labels: self-adhesive, often laminated, to be completed (date, technician, equipment ID). Colour coding or periodicity for metrology checks, maintenance, fire safety. Indelible inks; substrates resistant to solvents and disinfectants.

• Other signage: evacuation plans, door strips, safety mirrors, restricted-access signs — always selected for legibility and compatibility with the environment.

Selection criteria: compliance (ISO 7010, CLP), environment (indoor/outdoor, cold, cleanroom), substrate (painted, stainless steel, glass), chemical/abrasion resistance, adhesive (permanent, repositionable), reading distance and contrast, need for photoluminescence and traceability.

In which settings is laboratory safety signage used?

• Life sciences: BSL areas, PPE reminders, safety showers/eyewash stations, sample and waste flows.
• Pharmaceutical/biotech: GMP labelling of clean/dirty flows, cleaning instructions, restricted access.
• Food industry: hygiene, allergens, raw-to-finished product flows, anti-slip flooring.
• Chemistry/cosmetics: CLP labelling on containers, corrosive/flammable pictograms, LOTO during maintenance.
• Environment: hazardous waste storage, evacuation routes, sampling zones.
• QC laboratories: metrology inspection labels, equipment status (compliant/out of service).
• Cleanrooms: low-outgassing substrates, cleanroom-grade adhesives, zone colour-coding.
• Plant/utility rooms: isolation/lockout, energy source and hazard signage.

Available signage options

Frequently asked questions about laboratory safety signage

Which standard applies to on-site safety pictograms?
Safety pictograms follow ISO 7010 (shapes/colours). For chemicals, labelling falls under the CLP/GHS regulation.

How do I choose the size of a sign or pictogram?
Match it to the viewing distance, any obstructions and the lighting. Follow the manufacturer's guidance and ISO principles to ensure legibility and contrast.

Self-adhesive vinyl or rigid panel: which should I choose?
Vinyl suits doors, glazing and equipment. Rigid PVC or aluminium are best for walls and high-traffic areas.

What is photoluminescent signage for?
It remains visible in the dark to guide evacuation if the lighting fails. Ideal for exits, obstacles, emergency equipment and low-level wayfinding.

What does a lockout/tagout (LOTO) procedure involve?
Locking devices, padlocks, personalised tags and a written procedure. It prevents any re-energisation during maintenance.

Do inspection labels withstand solvents?
Choose PP/PE substrates or laminated vinyl and indelible inks. Check compatibility with your routine disinfectants and solvents.

When should signage be replaced?
As soon as it is damaged or unreadable, or if risks change. An annual signage audit helps maintain compliance.
