Why Water Safety Is a Non-Negotiable Priority

Water on set introduces hazards that don't exist in dry production environments. Drowning risk, electrical hazards, hypothermia, slip-and-fall injuries, and equipment failures all become live concerns the moment water enters the production space. These risks are entirely manageable with proper planning — but they demand respect, preparation, and clear protocols before a single drop is introduced to the set.

Pre-Production Safety Planning

Water sequences require a dedicated aquatic safety plan as part of the overall production risk assessment. This plan should be developed in collaboration with:

  • The SFX supervisor responsible for the water effects
  • A qualified stunt coordinator if performers are in or near water
  • A certified aquatic safety consultant or safety diver team
  • The production's health and safety officer
  • The director of photography (for electrical and lighting considerations)

The plan must identify every water-adjacent hazard, define the chain of command for safety decisions, and establish clear abort procedures for all water-based setups.

The Non-Negotiables: On-Set Water Safety Rules

Never Work Without a Safety Diver

Any time performers, operators, or crew are working in or near water deeper than waist height, at least one certified safety diver must be in the water and dedicated solely to monitoring — not operating equipment or assisting with the shot. Two divers are strongly recommended for tank work involving stunts.

Electricity and Water Do Not Mix

All electrical equipment near water must be:

  • Protected by ground fault circuit interrupters (GFCIs)
  • Positioned at a safe distance from the water's edge as defined by local electrical codes
  • Inspected by a qualified electrician before any wet tests
  • Switched off and locked out before any personnel enter the water

There are no exceptions to this rule. Electrical incidents in water are almost always fatal.

Temperature Management

Cold water presents a serious hypothermia risk, even in relatively short exposure. Productions should:

  • Specify a minimum water temperature appropriate for performer exposure time
  • Have drysuits or wetsuits available for extended water work
  • Set strict maximum continuous water exposure limits per performer
  • Provide warm dry areas, towels, and heated changing facilities on standby

Slip and Fall Prevention

Wet floors cause more on-set injuries than any other water hazard. All wet walking surfaces should be covered with non-slip matting. Colour the matting in high-visibility yellow or orange so crew can identify wet zones at a glance. Crew working in or around water should wear appropriate non-slip footwear.

Communication and Abort Signals

Before any water sequence begins, every crew member present must be briefed on the abort signal — a universally understood visual or audible signal (typically a horn or whistle combined with a raised fist) that immediately stops all water flow, cuts power, and clears personnel from the water. This signal should be demonstrated in the briefing, not just described.

Post-Shoot Water Removal

Standing water left on set after a shoot creates ongoing slip hazards, electrical risks, and potential structural damage. Designate a crew responsible for water removal before the set is handed back or reused. Document the condition of the space after water has been removed and report any water damage immediately to production management.

Documentation and Permits

Many jurisdictions require specific permits for water use on location, especially when large volumes are involved or when discharge into public waterways may occur. Your location manager and safety officer should identify and secure all required permits well before the shoot date.
