Corporate Procedure: CP-WMS 009                  Authorised by:

Issue number:           Two                      Date of issue:          12th May 2010

Purpose
To define the University of Sheffield’s emergency procedures associated with Cofield Swimming
Pool.

Scope

This procedure applies to Cofield Pool.

Legal Framework

Water Industry Act 1991
Health and Safety at Work Act 1974
Control of Substances Hazardous to Heath Regulations 2002
Health and Safety at Work Regulations 1999

Responsibilities

Technical services / Swimming Pool Maintenance Technicians – Day to day running of the pool.

Assistant Electrical Engineer – Maintenance of plant, equipment and machinery.

U Sport Facilities manager and U Sport Employees – To ensure that emergencies are reported
to the relevant members of staff and recorded using corporate systems.

Environment Officer – Legal compliance and internal audit.
Procedure
1.         Vomit or Faecal Release / Emergency Backwashing

1.1.    Upon the discovery of either vomit, faecal matter or any other hazardous material in the
pool, poolside attendants must clear the pool of bathers immediately and alert the technical
staff.

1.2        Poolside Attendants should instruct all bathers to shower thoroughly.

1.3    An emergency backwash is required for releases of a runny stool (diarrhoea), vomit or
animal faeces the pool must be closed for a 24 hour period and the following course of action
should be taken

      1.   Chlorine levels should be maintained at 2ppm for the period of time it takes to complete
           the emergency backwash,
      2.   Vacuum or sweep the pool – poolside attendants are responsible for this.,
      3.   Filter the pool for six turnover cycles using continuous coagulation,
      4.   Back wash the filters,
      5.   Check the final disinfectant residual level and pH value of the pool water,
      6.   Reopen the pool.

1.4        Only technical staff are trained to carry out emergency backwashing.

1.5        Poolside attendants are responsible for completing the accident report book.

1.6   Technical staff should make a note of the incident in their day book and inform the
Mechanical Engineer that an emergency backwash has been necessary.

2.         Release of Chlorine Gas

2.1    When calcium hypochlorite tablets come into contact with water, oil or carbonated
drinks chlorine gas is released. Chlorine gas is a heavy highly irritant gas, which, even in small
doses causes running eyes and a choking cough, large doses will be fatal.

2.2        The consumption of food and drink in the plant room is prohibited.

2.3        Oil must not be stored in the plant room under any circumstances.

2.4      Calcium hypochlorite tablets must be stored in the plastic containers they are supplied
in. Lids should always be placed securely back on containers immediately after use.

2.5        Calcium hypochlorite tablets must not be stored by the water main in the plant room.

2.6     All deliveries of calcium hypochlorite tablets must be overseen by a member of technical
staff. Damaged containers must be rejected and retuned to the supplier.

2.7      PPE, including chemical resistant gloves, should be stored near the calcium hypochlorite
tablets.

2.8   Should chlorine gas be released in the plant room the following procedure should be
adopted:

     1. Evacuate the immediate area at once.
     2. If safe to do so, remove any casualty (wearing correct personal protective equipment) to
        fresh air and render first aid.
     3. Again if safe to do so, ventilate area by opening doors and windows.
     4. Inform the Mechanical Engineer.
     5. If necessary evacuate the building, if this is done using the fire alarm then contact the
        Control Centre to inform them that the emergency is not a fire.
     6. Identify the cause of the chlorine gas. If large volumes of gas are present, request fire and
        emergency services by dialling 4444 from an internal phone. Inform the emergency
        services of the presence of poisonous gas so they can come prepared to deal with the
        situation.
     7. Only renter the contaminated area when safe to do so.

2.9    Technical staff should make a note of the incident in their day book and the Mechanical
Engineer must complete the accident report rook.

3.      Power Failure

3.1    If a power failure causes the dosing equipment and circulation pumps to temporarily
stop working the pool should be closed.

3.2   Technical staff should inform the Facilities Manager that the pool needs to be
temporarily closed.

3.3    Once the power has been returned the chemical properties of the pool water should be
tested using tablet tests.

3.4     If levels are within range the pool can be reopened. If not, then steps should be taken to
bring the levels within the acceptable range before the pool is reopened.

4.      Failure of Dosing Equipment

4.1       If the automatic calcium hypochlorite dosing equipment fails the Mechanical Engineer
will liaise with the Facilities Manager to decide if the pool should be closed or if it can remain
open by adding calcium hypochlorite manually to the pool.

4.2     If the pool is to remain open tablet test kits should be used to monitor the chlorine levels
in the pool water. When the results indicate that manual dosing is required technical staff will
liaise with poolside attendants and temporarily close the pool (for approx 30mins).

4.3   Once the pool has been cleared of bathers, calcium hypochlorite tablets can be added
manually to the pool.

4.4   Tablet tests should be undertaken to check levels before reopening the pool and bathers
readmitted.

4.5     The CO2 dosing equipment operates using cylinder pressure, and will only fail if the if the
gas cylinder is damaged or the tubing is damaged.

4.6   CO2 can not be manually dosed. A spare co2 gas cylinder should always be kept and
damaged tubing should be repaired / replaced as soon possible.
