  CO Detection - Commercial vs. Residential Applications  
 

OSHA does not permit employees to be exposed to more than 50 ppm of carbon monoxide (CO) in the workplace.  NIOSH recommends limiting exposure to 35 ppm.  Both workplace exposure limits are averaged over 8 hours.

The UL 2034 residential standard requires that CO alarms activate an alarm signal by 70 ppm within 1-4 hours, but does not permit residential CO alarms to activate an alarm at CO levels below 30 ppm for 30 days.  Residential CO alarms listed to UL 2034 are intended for use in ordinary indoor locations of family living units, and are not designed to measure compliance with OSHA, commercial or industrial standards.

The Pro-Tech 8505 Commercial CO Monitor should be installed within all conditioned workplaces that have a gas or oil fueled furnace, boiler, water heater or appliance.  The Pro-Tech 70 Series Carbon Monoxide Alarms should only be installed within residential dwellings.
