# Important safety information

The Pulse equipment has been designed and manufactured to meet strict international safety standards. Like any electrical and pressurised apparatus, due care must still be taken when operating the equipment.

<Danger>
  For your safety, all relevant national safety regulations must be complied with relating to pressurised and electrical systems when using the equipment.
</Danger>

## Intended use of Pulse

Pulse is exclusively intended for determining the air leakage and/or background air change rates of buildings and enclosures. The Pulse equipment must be stored in a dry, stable environment; protected at all times from extreme conditions and weather.

Pulse must be operated only as intended in this user documentation and within the constraints of the technical specifications found on the <a href="/technical/equipment-specification">Equipment specification</a> page and/or on the power rating label on the device itself.

<Warning>
  Any equipment usage that does not comply with the technical specification or user operation detailed in this documentation will void your warranty.
</Warning>

## Recommended safety equipment

The noise level when air is released from an air receiver can be relatively loud. We recommend wearing ear protection or earplugs, especially when doing many tests in a day.
