FIRE SAFETY
Fire doorsets for corridors can be held open with an electro-magnetic device, but safely self-close when activated by smoke detectors or a main fire alarm system.
Inclusivity in action Fire doorsets for corridors can be held open with an electro-magnetic device, but safely self-close when activated by smoke detectors or a main fire alarm system. They must also close should the power supply fail, or when activated by a hand- operated switch. Meanwhile, fire doorsets for individual rooms could be fitted with swing-free devices that – again – close when activated by smoke detectors, a fire alarm system, or when the power supply fails.
Door-opening solutions can potentially be a common barrier to inclusive design.
This challenge might arise because someone is a wheelchair user, or a parent with a young child using a pushchair. Alternatively, it could be due to physical changes that occur throughout the ageing process – which might include deterioration of sight, hearing loss, a decline in respiratory and cardiovascular functions, or reduced muscle and grip strength – as an older member of society. Nevertheless, carefully considering door-opening solutions can make a real difference to the inclusivity of a space, and is a ‘non-negotiable’ when planning for fire safety.
Opening and closing forces One key consideration that needs to be taken into account to comply with BS 8300-2:2018 is opening and closing forces. To enable independent access through a door, the opening force – when measured at the leading edge of the door – should be no greater than 30 N, when moving from the closed position to 30° open. Then, the opening force required from 30° to 60° should be no more than 22.5 N. Finally, in terms of the maximum closing force exerted by a controlled door-closing device, this should be within 0° and 15° of final closure.
Door fittings need to be properly
considered too. Door opening furniture should be easily reached and provide a secure grip to users. This is critically important to many people with a disability. It should be possible to operate door furniture one-handed, without the need to grasp or twist, or ‘skinning’ your knuckles.
