Everyone is always asking if there are temperature requirements for this and that. Well, yes and no. Here’s what our research has found:
With regard to water in schools, the only requirement that I could find was in Title 22, Div 12, Article 7 (Child Care Facility Regulations) Section 101239(e)(1) to keep hot water between 105-125 degrees F for personal care faucets. Technically, you will need a warning sign if the water temperature is over 125 degrees, but as a good risk management practice, you should placard it anyway.
Here’s some of the codes:
(e) Faucets used by children for personal care shall deliver hot water.
(1) Hot water temperature controls shall be maintained to automatically regulate temperature of hot water delivered to plumbing fixtures used by children to attain a hot water temperature of not less than 105 degrees F (40.5 degrees C) and not more than 120 degrees F (48.8 degrees C).
(2) Taps delivering water at 125 degrees F (51.6 degrees C) or above shall be prominently identified by warning signs.
(3) Notwithstanding (e) and (e)(1) above, handwashing fixtures shall not be required to deliver hot water.
(4) All toilets, handwashing and bathing facilities shall be maintained in safe and sanitary operating condition. Additional equipment, aids and/or conveniences shall be provided as needed in centers that serve children with physical disabilities.
The Child Care Regulations Section 101239 requires a temperature between 68-85 degrees F for air temperatures in Child Care Classrooms.
(a) A comfortable temperature for children shall be maintained at all times.
(1) The licensee shall maintain the temperature in rooms that children occupy between a minimum of 68 degrees F (20 degrees C) and a maximum of 85 degrees F (30 degrees C).
(A) In areas of extreme heat the maximum shall be 20 degrees F (11.1 degrees C) less than the outside temperature.
ASHRAE provides us with guidance on general classroom temperatures in their Standard 62.1-2007. They suggest that the temperatures for classrooms should be based on the season. 68-76 winter; 72.5-80 summer.
ASHRAE/ ANSI Standard 55-2004, “Thermal Environmental Conditions for Human Occupancy” This standard is designed such that 80% of the occupants will find the temperature to be acceptable. So, it does not truly set a temperature, but states that if 80% of the occupants say it is fine, then it is fine.
Cal/OSHA has no minimum temperature standards outside of Section 3366, however, section Section 5142 states that you will need to run your HVAC system to ensure that you are getting fresh air to your staff. These really aren’t about temperature, but supply good quality air to workers.
5142. Mechanically Driven Heating, Ventilating and Air Conditioning (HVAC) Systems to Provide Minimum Building Ventilation – This deals with quantity of ventilation delivered as required by theCA Building Code at the time the building was permitted.
Title 8, Cal-OSHA, provides for a minimum of 85 degree F water temperature if certain conditions apply, see the bold section below in quotes.
