Halloween scares should come from costumes and maybe movies (actual scary movies, mind you, and not the horribly directed ones), and not from real-life hazards lurking in the workplace. From fog machines to flammable decorations, unnoticed dangers can creep in. In this guide, we'll help you safely enjoy the Halloween celebrations with simple tips to protect your team and your compliance.

Key Points

  • Hidden hazards appear when workplaces decorate for Halloween: Seasonal décor and altered lighting can introduce risks that aren't part of everyday safety controls.
  • Costumes can compromise visibility and mobility: Oversized accessories make it harder for workers to move safely and respond quickly in an emergency.
  • Flammable materials and open flames remain a major fire risk: Synthetic fabrics can ignite faster than expected without proper controls.
  • Fog machines and themed chemicals require COSHH compliance: Even one-night products must still be logged, assessed, and ventilated appropriately under UK regulations.
  • Clear accountability prevents festive chaos from turning into real danger: Assigning roles for setup and cleanup keeps fun events safe and compliant.

Halloween scares lurking in workplaces

Even the smallest change in environment, such as a cape sleeve near a candle or a fog machine in a tight corridor, can create very real risks. Here are the most common Halloween scares that sneak into UK workplaces when celebrations begin.

Halloween Scare 1: Decorations that turn into fire hazards

Seasonal décor, like fake cobwebs, can be highly flammable, especially when hung near warm equipment or electrics. Add candles, lanterns, or plug-in lighting and the risk only grows. Fires can spread shockingly fast in cluttered or temporary displays that weren't evaluated for risk.

⚠️ Why this often gets overlooked: Decorations are seen as harmless fun, not as items that must meet fire-safety standards in a workplace.

Halloween Scare 2: Costumes that limit vision and mobility

Masks can tunnel vision. Capes or floor-length outfits can snag and cause you (or others) to trip. Some costumes can even prevent people from wearing required PPE.

⚠️ Why this often gets overlooked: Costumes are chosen for fun first, with safety rarely factoring into dress-up decisions.

Halloween Scare 3: Seasonal chemicals forgotten in COSHH files

Fog machines, theatrical smoke, fake blood, UV paints, and certain glues all introduce chemical hazards. Even if used “just for one night,” UK employers must still assess and control exposure under COSHH. Without ventilation or proper handling, these substances can trigger asthma and other reactions.

⚠️ Why this often gets overlooked: Temporary products feel “too small” to document. This is a "minor” mistake that can leads to significant compliance gaps.

Halloween Scare 4: Dim lighting that hides hazards

Darkened rooms are great for atmosphere, but are terrible for hazard perception. Visual impairments from masks or flashing lights can make risks even harder to detect.

⚠️ Why this often gets overlooked: Creating a “spooky” atmosphere often overshadows being safe overall.

Halloween Scare 5: Unclear roles when something goes wrong

When celebrations disrupt routine, accountability can slip. Staff assume someone else handled checks. A delayed response amplifies harm, even during minor incidents.

⚠️ Why this often gets overlooked: People focus on organising the event, not assigning who's in charge of keeping it safe.

No Tricks, Just Safe Treats: A Halloween Workplace Safety Checklist

Before the celebration begins:

  • ✅ Keep all decorations away from heaters, electrics, and open flames
  • ✅ Ensure pathways, stairs, and fire exits remain clear of props and cables
  • ✅ Confirm costumes are flame-resistant and allow safe movement
  • ✅ Make sure masks maintain clear vision, or swap for face paint
  • ✅ Double-check PPE can still be worn properly with costumes
  • ✅ Add any fog fluids, UV paints, sprays, or adhesives to COSHH documentation
  • ✅ Assign someone responsible for safety checks and fire marshaling

During festivities

  • ✅ Avoid overcrowded or poorly lit shortcuts; use marked crossings outdoors
  • ✅ Prevent tripping by fixing loose costume pieces
  • ✅ Stay cautious around smoke machines and dark corridors. Ensure ventilation
  • ✅ Make sure PPE is put back on immediately after photos
  • ✅ Check that emergency exits stay unobstructed as decorations shift

After the fun

  • ✅ Properly store or dispose of any chemicals used for the event
  • ✅ Record any observations, near-misses, or needed improvements
  • ✅ Switch off all electrics and extinguish flame sources before leaving

Real hazards on Halloween

Every year on Halloween, children and adults in the UK are injured when candles or fireworks ignite costumes or hair. Dorset & Wiltshire Fire & Rescue Service notes that plastic capes or bin-liners, which are often used as costumes, can engulf the wearer in flames in as little as nine seconds once ignited.

💡 Lesson: Verify costume flammability, avoid naked flames near decorations, and treat every prop like a risk.

Frequently Asked Questions (FAQ)

1. What are the best Halloween workplace fire safety tips for office celebrations?

To prevent fire risks during Halloween, keep all decorations away from heat sources and electrical equipment. Ensure emergency exits and fire extinguishers remain fully accessible and visible. Designate a responsible person to check lighting and cables, for overheating throughout the event.

2. How can employers reduce chemical exposure from fog machines and Halloween sprays at work?

Always follow the manufacturer's instructions when using fog machines or aerosol sprays, and keep them out of confined or poorly ventilated rooms to reduce respiratory irritation. Confirm that any chemical product used during the event is included in your COSHH assessment, with safety data available to employees. If someone has asthma or breathing sensitivities, provide alternative areas away from fog effects to keep the celebration inclusive and safe.

3. What costume safety rules should workplaces set for Halloween events?

Costume guidelines help prevent accidents on the spookiest day of the year. Avoid trailing fabrics or any sharp accessories. Ensure PPE remains usable and not obstructed by costumes for those who need it. For staff who work around flames, or chemicals, flame-retardant and properly fitted costumes are a must.

4. How do businesses update COSHH requirements for Halloween decorations and cleaning products?

Any new substance introduced for Halloween must be logged in your COSHH inventory and reviewed for potential hazards. Even short-term items may require additional PPE or ventilation controls. Safety Data Sheets should be accessible to staff, and supervisors must brief teams on any new risks before the celebrations begin.

5. How can workplaces keep exits and walkways safe during Halloween office parties?

Clear escape routes are non-negotiable. No decoration should block emergency signage or exit doors. Check that cables from lights or fog machines are secured to avoid trips, and avoid placing decorations in stairways and near high-traffic areas. Assign someone to monitor pathways throughout the event to maintain a hazard-free and regulation-compliant environment.
