Swimming Pool Chemicals

Code Compliance Guideline

and Fire Safety Requirements Related to Pool Operations

This page outlines the Virginia Statewide Fire Prevention Code (VSFPC) requirements related to the dispensing, storage, and use of common swimming pool chemicals (e.g., corrosive liquids and oxidizers) at water recreation facilities such as public swimming pools and waterparks located in Fairfax County and the towns of Clifton, Herndon, and Vienna. Fire safety requirements common to water recreation facilities and the roles and responsibilities of pool operators and lifeguards are also addressed in this publication. 
 
Questions regarding the content of this publication should be directed to the Fire Inspections Branch at 703-246-4849 during regular office hours, Monday thru Friday, 8:00 a.m. to 4:30 p.m.
 

HAZARDOUS MATERIALS (Pool Chemicals)

Safety Data Sheets (SDS) Required. SDS for all hazardous materials shall be either readily available on the premises as a paper copy or readily retrievable by electronic access. SDS should be stored in a non-hazardous area such as an office or lifeguard room and not in pool chemical dispensing and storage areas. It is suggested that SDS be kept in a dedicated binder or folder which is clearly marked "SDS" for easy identification. SDS can be obtained from the pool chemical supplier.  (VSFPC 407.2)
 
Individual Container Identification Required. Individual containers of hazardous materials, cartons or packages shall be clearly marked or labeled in accordance with applicable federal regulations.  (VSFPC 407.3)

  • All containers and packages should be properly sealed or closed and safely stored in accordance with the SDS to prevent leakage, exposure, or possible injury. In addition, containers should be safely stored on spill containment decking or pallets. 

 
NFPA 704 Hazard Identification Signs Required. NFPA 704 hazard identification signs shall be provided at entrances to locations where pool chemicals are stored, dispensed, used. or handled in quantities requiring a permit and at specific entrances and locations designated by the fire code official.  (VSFPC 5003.5)

  • NFPA 704 signs shall be numbered and labeled for the hazards associated with the pool chemical(s). Numbering and labeling information is typically found in the MSDS. Where many chemicals are present, a single sign shall summarize the maximum ratings contributed by the material(s) in each category and the special hazard category for the building and/or the area. NFPA 704 signs may be obtained through industrial safety equipment suppliers, sign fabricators, or sign supply companies.  (See Example on Page 2)

 
NFPA 704 Sign Maintenance & Visibility. NFPA 704 signs and markings shall not be obscured or removed, shall be in English as a primary language or in symbols permitted by the Fire Prevention Code, shall be durable, and the size, color and lettering shall be approved.  (VSFPC 5003.6)

Hazard Identification Sign and Markings

Separation of Incompatible Materials Required. Incompatible materials are materials that, when mixed, have the potential to react in a manner which generates heat, fumes, gases, or byproducts which are hazardous to life or property. Material incompatibility information is typically found in the SDS. All materials in storage and storage of materials that are incompatible with materials in use shall be separated when the stored materials are in containers having a capacity of more than 5 pounds or 1/2 gallon. Separation of incompatible materials shall be accomplished by any of the following:  (VSFPC 5003.9.8)
 

  1. Segregating incompatible materials in storage by a distance of not less than 20 feet.
  2. Isolating incompatible materials in storage by a noncombustible partition extending not less than 18 inches above and to the sides of the stored material.
  3. Storing liquid and solid materials in approved hazardous material storage cabinets.

Security of Hazardous Materials Required. Storage, dispensing, use and handling areas shall be secured against unauthorized entry and safeguarded in an approved manner.  (VSFPC 5003.9.2)

Secondary Containment Required for Corrosive Liquids. Secondary containment is a level of containment that is external to and separate from primary containment. Buildings, rooms, or indoor areas where hazardous material liquids (e.g., Sodium Hypochlorite, Muriatic Acid) are dispensed or used in open systems shall be provided with secondary containment when the capacity of an individual vessel or system is greater than 1.3 gallons or the capacity of multiple vessels or systems is greater than 5.3 gallons.  (VSFPC 5005.2.1.4)
 
Storage of Class 2 Oxidizers. Storage of Class 2 oxidizers such as Calcium Hypochlorite (50% or less by weight) and Bromine shall be limited to no more than 250 pounds in any control area within a building not protected with an automatic sprinkler system. This may be increased to no more than 500 pounds where an automatic sprinkler system is provided.  (VSFPC 5003.1.1)  
 
Release of Hazardous Materials Prohibited. Hazardous materials in any quantity shall not be released into a sewer, storm drain, ditch, drainage canal, creek, stream, river, lake or tidal waterway or on the ground, sidewalk, street, highway or into the atmosphere.  (VSFPC 5003.3)

 

POOL OPERATORS & LIFEGUARDS

Hazardous Materials Familiarization & Training Requirements. Persons responsible for the operation of areas in which hazardous materials are stored, dispensed, handled, or used shall:

  1. Be familiar with the chemical nature of the materials and the appropriate mitigating actions necessary in the event of a fire, leak, or spill.  (VSFPC 407.4, 5003.9.1)
  2. Be trained to liaison with the fire department which includes preplanning emergency responses and identification of the locations of hazardous materials.  (VSFPC 407.4, 5003.9.1.1)
  3. Have access to Safety Data Sheets (SDS).  (VSFPC 407.4, 5003.4)
  4. Be knowledgeable in the on-site emergency response procedures.  (VSFPC 407.4, 5003.9.1.1)

 
Notification of Emergency Responders (Call 911). In accordance with sections 401.3 and 5003.3.1 of the Virginia Statewide Fire Prevention Code, notification of emergency responders shall be as follows:

  1. Fire Events & Alarm Activations. In the event an unwanted fire occurs on a property or upon activation of a fire alarm signal, pool operators and/or lifeguards shall immediately notify the fire department by calling 911.
  2. Hazardous Materials Release. Any person who witnesses, discovers, or otherwise has knowledge of a spill, leak or other release of a hazardous material or other material that may negatively impact the environment, regardless of quantity, shall immediately report such spill, leak or release to the Department of Public Safety Communications (Call 911) and to the Office of the Fire Marshal by calling 703-246-4386 (Leave a Message).

To learn more about hazardous materials discharge/spill notification procedures, visit the Fairfax Joint Local Emergency Planning Committee (FJLEPC). 
 
Emergency Procedures. Pool operators and lifeguards shall be able to reasonably articulate the following procedures related to the release or spill of hazardous pool chemicals:
 1. Evacuate the pool, pool deck, and pool house. Direct persons to a safe area.
