It is not common practice today to have an operative (caretaker) living on the site and therefore available to reset the boilers after a power cut, so the following section from the document is intended to overcome potential issues such as preventing pipes freezing. It also aims to minimise closures because the building has cooled after a power cut, perhaps the night before.

In section 3.1.8 boiler/plant rooms are covered by the following:
“School boiler/plant rooms are considered as areas of high fire risk. For this reason, the following fire safety precautions are required for new schools and where an existing boiler/plant room is upgraded or refurbished”

This section of the document then goes on to state that a boiler house attached to the main school building should be fitted with combustible gas and carbon monoxide detection. It also states that a pressure proving system can auto reset after a power cut so that the boilers can restart automatically.

Only the boilers for the heating of the school can have the gas supply on auto reset after a power cut.

The fresh air background Carbon Dioxide (CO₂) level is typically between 350-450 ppm. Within a building, without adequate ventilation, this level will rise considerably where there are people. The levels will tend to be higher in education buildings because the occupancy is higher for a given reservoir of air in a classroom. The average adult (or older student) exhales an amount of carbon dioxide at a level around 35,000-50,000 ppm. This equates to about 0.01 grams per second (g/s) (about 0.005 l/s).

DfES Building Bulletin 101 – Ventilation of School Buildings
This supports the Building Regulations Part F in laying out the requirements for ventilation in schools particularly states that:
“ventilation should be provided to limit the concentration of carbon dioxide in all teaching and learning spaces so that when it is measured at seated head height, during the continuous period between the start and finish of teaching on any day, the average concentration of CO₂ should not exceed 1500 ppm.”

This is a limiting value and it requires that at any occupied time, including when teaching, the occupants should have the ability to lower the CO₂ concentration to 1000 ppm (by extra ventilation). CIBSE TM30 also recommends a limiting value of approximately 1000 ppm.
Bunsen burner use will also increase the CO₂ levels since a Bunsen burner will produce about double the amount of CO₂ produced by a student or teacher.
It should be noted that IGEM document UP11, Edition 2, “Gas for use in education establishments” allows for higher levels of CO₂ to be present in some teaching areas but that the BB101 is clear that the CO₂ level over the teaching day does not average more than 1,500 ppm.

Services on page 49:
“All services should have a master control panel, which should be located near the main teaching position. This allows the teacher to control access to services as required and also to shut off any or all in the event of an accident.”

In regard to education buildings references from IGEM publication, UP11, Edition 2 it’s worth having looking at.
