Employee alarm and fire detection system procedure covering the pull stations, horns, strobes, control panel, detectors, and sprinkler monitoring switches that make up the facility warning system, the requirement that the fire alarm be perceptible above ambient noise and distinct from every other signal, the testing cadence and records required by 29 CFR 1910.165(d), detector cleaning, adjustment, and impact protection under 29 CFR 1910.164, coordination with the central station monitoring company and advance notice to employees before every audible test, and the handling of panel trouble and supervisory signals as same-day work orders.
- Audience
- The facility or safety manager who owns the alarm and detection program, maintenance technicians who respond to panel signals and escort the servicing contractor, shift supervisors who relay test notices to their crews, and all warehouse employees for the purpose of recognizing the alarm and reporting a damaged or troubled device

Fire Detection and Alarm System Testing: 29 CFR 1910.38(d)
Every SOP generated from this template cites the paragraphs below, with a plain-language summary of what each one requires. Citations are informational and are not legal advice.
The employer shall assure that all devices, components, combinations of devices or systems constructed and installed to comply with this standard are approved.
| Standard | Title | What it requires |
|---|---|---|
| 29 CFR 1910.38(d) | Emergency action plans: employee alarm system | An employer must have and maintain an employee alarm system. The employee alarm system must use a distinctive signal for each purpose and comply with the requirements in 29 CFR 1910.165. Because this facility's emergency action plan requires an employee alarm system, this paragraph is what makes 1910.165 apply to the alarm covered by this procedure. |
| 29 CFR 1910.165(b) | Employee alarm systems: general requirements | The employee alarm system must provide warning for necessary emergency action as called for in the emergency action plan, or for reaction time for safe escape of employees. The alarm must be capable of being perceived above ambient noise or light levels by all employees in the affected portions of the workplace, and tactile devices may be used to alert employees who would not otherwise be able to recognize the audible or visual alarm. The alarm must be distinctive and recognizable as a signal to evacuate the work area or to perform actions designated under the emergency action plan. The employer must explain to each employee the preferred means of reporting emergencies, such as manual pull box alarms, public address systems, radio, or telephones, and must establish procedures for sounding emergency alarms; for an employer with 10 or fewer employees in a particular workplace, direct voice communication is an acceptable procedure. |
| 29 CFR 1910.165(c) | Employee alarm systems: installation and restoration | All alarm devices and systems installed to comply with the standard must be approved; steam whistles, air horns, strobe lights or similar lighting devices, and tactile devices meeting the requirements of the section are considered to meet the approval requirement. The employer must restore the employee alarm system to normal operating condition as promptly as possible after each test or alarm, and spare alarm devices and components subject to wear or destruction must be available in sufficient quantities and locations for prompt restoration of the system. |
| 29 CFR 1910.165(d) | Employee alarm systems: maintenance and testing | The employee alarm system must be maintained in operating condition except when undergoing repairs or maintenance. A test of the reliability and adequacy of non-supervised employee alarm systems must be made every two months, and a different actuation device must be used in each test of a multi-actuation device system so that no individual device is used for two consecutive tests. Power supplies must be maintained or replaced as often as necessary to assure a fully operational condition, with a back-up means of alarm, such as employee runners or telephones, provided when systems are out of service. Employee alarm circuitry installed after January 1, 1981 that is capable of being supervised must be supervised, must provide positive notification to assigned personnel whenever a deficiency exists in the system, and supervised systems must be tested at least annually for reliability and adequacy. Servicing, maintenance, and testing of employee alarms must be done by persons trained in the designed operation and functions necessary for reliable and safe operation of the system. |
| 29 CFR 1910.164(b) | Fire detection systems: installation and restoration | This section applies by its terms to automatic fire detection systems installed to meet the requirements of a particular OSHA standard. All detection devices and equipment installed to comply with the standard must be approved for the purpose for which they are intended. The employer must restore all fire detection systems and components to normal operating condition as promptly as possible after each test or alarm, and spare detection devices and components that are normally destroyed in the process of detecting fires must be available on the premises or from a local supplier in sufficient quantities and locations for prompt restoration of the system. |
| 29 CFR 1910.164(c) | Fire detection systems: maintenance and testing | Fire detection systems must be maintained in an operable condition except during repairs or maintenance. Fire detectors and detection systems must be tested and adjusted as often as needed to maintain proper reliability and operating condition, except that factory calibrated detectors need not be adjusted after installation. Pneumatic and hydraulic operated detection systems installed after January 1, 1981 must be equipped with supervised systems. Servicing, maintenance, and testing of fire detection systems, including cleaning and necessary sensitivity adjustments, must be performed by a trained person knowledgeable in the operations and functions of the system, and fire detectors that need to be cleaned of dirt, dust, or other particulates in order to be fully operational must be cleaned at regular periodic intervals. |
| 29 CFR 1910.164(d) | Fire detection systems: protection of fire detectors | Fire detection equipment installed outdoors or in the presence of corrosive atmospheres must be protected from corrosion, with a canopy, hood, or other suitable protection provided for detection equipment requiring protection from the weather. Detection equipment must be located or otherwise protected so that it is protected from mechanical or physical impact which might render it inoperable, and detectors must be supported independently of their attachment to wires or tubing. |
