Gas Detectors require regular maintenance service. These detectors typically use Electro-Chemical (EC) sensors, that are similar to a battery, in design. Most Electro-Chemical (EC) sensors have a typical shelf and working life of 2-3 years. Manufacturers place date codes on each sensor that indicate the year of manufacture. Sensors should be replaced at regular service intervals to prevent failure during use.
Typical maintenance service includes: sensor replacement, filter replacement, pump cleaning, battery and sample tube replacement. Safety Instruments provides a written estimate that itemizes all labor and parts required prior to performing any repairs. As outlined in OSHA 1910.146(d)(4), the employer must provide equipment that is properly maintained.
