IMPORTANT NOTICE TO OUR CUSTOMERS

Civic Center Staff would like to inform our customers and patrons about the precautions and safety measures we are taking regarding carbon monoxide exposure. The local Fire Marshall has conducted testing in the ice rink and the results were 2-4ppm with a peak of 10ppm. These numbers are well below the Occupation Safety and Health Guideline for Carbon Monoxide exposure limits, which can be found below. In addition to the testing done by the Fire Marshall we also have two carbon monoxide detectors that are tested montly. Also in case of an emergency, members of the Civic Center staff are trained in first aid and in the use of our on site defibrillator unit.

Occupational Safety and Health Guideline for Carbon Monoxide

EXPOSURE LIMITS

* OSHA PEL

The current Occupational Safety and Health Administration (OSHA) permissible exposure limit (PEL) for carbon monoxide is 50 parts per million (ppm) parts of air (55 milligrams per cubic meter (mg/m(3))) as an 8-hour time-weighted average (TWA) concentration [29 CFR Table Z-1].

* NIOSH REL

The National Institute for Occupational Safety and Health (NIOSH) has established a recommended exposure limit (REL) for carbon monoxide of 35 ppm (40 mg/m(3)) as an 8-hour TWA and 200 ppm (229 mg/m(3)) as a ceiling [NIOSH 1992].

* ACGIH TLV

The American Conference of Governmental Industrial Hygienists (ACGIH) has assigned carbon monoxide a threshold limit value (TLV) of 25 ppm (29 mg/m(3)) as a TWA for a normal 8-hour workday and a 40-hour workweek [ACGIH 1994, p. 15].

* Rationale for Limits

The NIOSH limit is based on the risk of cardiovascular effects [NIOSH]

The ACGIH limit is based on the risk of elevated carboxyhemoglobin levels [ACGIH 1991, p. 229].
