1 NDL使用氣體、TLV、設定警報值、氣味
The MAK(maximum workplace concentrations, same as TLV, threshold limit value) value is defined as the maximum concentration of a chemical substance (a gas, vapour or particulate matter) in the workplace air which generally does not have known adverse effects on the health of employees nor causes unreasonable annoyance (e.g. by nauseous odour), even when a person is repeatedly exposed during long periods, usually for 8 hours daily but assuming on average a 40-hour working week. Threshold limit value − short-term exposure limit (TLV-STEL): spot exposure for a duration of 15 minutes, that cannot be repeated more than 4 times per day with at least 60 minutes between exposure periods Threshold limit value − ceiling limit (TLV-C): absolute exposure limit that should not be exceeded at any time Flammability = Explosive ?
