Safety around the water maze

Water, electricity and long days of bending over a pool. Look after yourself too.

It's easy to plan every detail for the animals and forget the person running the trials. The original site gave safety its own section, from primer paint to ladders to pool height, and you can read it in full in Part II, HVS user hints. The questions below bring it up to date.

: Please talk to your Health & Safety adviser before setting up a water system.

Questions people ask

How do I protect myself from laboratory animal allergy?

Animal allergy is common. Use the ventilation, gloves, lab coat and mask your risk assessment specifies, avoid dry sweeping, and join your occupational health surveillance. Report symptoms early. Your local ethics committee, licence conditions and vet always take precedence.

More detail

11–44% of exposed workers report allergic symptoms [Bush & Stave 2003]. HSE: control under COSHH, ventilated enclosures, RPE, wet cleaning or Type H vacuum, health surveillance [HSE EH76; HSE asthma].

Going deeper

Early reporting matters because occupational asthma can become permanent [HSE].

What electrical and slip hazards should I watch for around the pool?

Protect all mains equipment near the pool with an RCD (30 mA), test it before use, keep cables and connectors away from water, and mop up spills at once. Your local ethics committee, licence conditions and vet always take precedence.

More detail

RCD at 30 mA or less, tested with its button; only a secondary safeguard; battery or reduced-voltage equipment in damp areas [HSE]. Slips and trips guidance [HSE]. Keep HVS platform connectors out of the water [HVS].

Going deeper

Lock castors; projecting castors are a trip hazard [HVS].

How do I set up the maze to avoid back strain?

Set the pool or table at a height where you can reach the animals without bending far. Never lift a filled pool: drain it first. Lock the castors. Your local ethics committee, licence conditions and vet always take precedence.

More detail

Poor working height causes back problems; a full pool can exceed 1.5 t [HVS]. Avoid hazardous manual handling where reasonably practicable, or assess it [HSE L23].

Going deeper

Illustrative: a 2 m pool with 30 cm of water holds about 0.94 t.

How do I avoid strain on long testing days?

Plan breaks, rotate tasks between people if you can, and use a comfortable, adjustable chair at the PC. Your local ethics committee, licence conditions and vet always take precedence.

More detail

Avoid strain by building in breaks, rotating tasks, and setting the pool, chair and computer at comfortable working heights. Repetitive work, awkward posture and long tasks without breaks cause upper limb disorders [HSE ULD]. Suitable seating [HSE HSG57].

Going deeper

Rotating people must be balanced across groups to avoid experimenter effects [Vorhees & Williams 2024].
