The use of conventional you it’s a pressure measurement such as inches of mercury or pounds per square inch. Would result in pressure expressed as a very small numbers. It’s more convenient to express pressure is to high to water column. That the pressure in the doctor will support . The PEL is OSHA is permissible exposure limit. The PEL is a highest concentration in air. I’ll be chemical substance to which employees may be exposed. The LEL or lower explosive limit is a much higher concentration at which the chemical gas or vapor will burn or explode. If an ignition source is present methyl alcohol for example : This is equivalent to a concentration of has an LEL = 6.7 % in air , 67000 per 10000000 more than 300 times higher than It’s PEL 200 per 10000000. Is a popular standing for indoor air quality. You’re probably heard a lot about this in recent past when we talk about indoor air quality problems we’re talking about improper
- Temperature
- High or Low Humidity
- oders
- Oxygen depletion
- Carbondioxide build – up or
- High concentration 0 other air contaminants
in the work place. Such as Tobacco smoke biological agents like mold spores or industrial chemicals normally the building’s and air conditioning systems are expected to control temperature , Humidity’s , oders , oxygen depletion , carbondioxide build-up , mold spores in tobacco smoke
