Ventilation in Shipyard Employment

Hazardous air contaminants come from two main sources (1) contaminants previously contained in the tanks or spaces; and (2) contaminants produced during shipbuilding,ship repair or shipbreaking.Typically,some of these contaminant-generating operations include welding,painting,blasting,or the use of solvents or cleaning products.Some results are removed in response to a notice of local law requirement.For more information,please see here.Previous123456NextDucting HRVs and ERVs Some results are removed in response to a notice of local law requirement.For more information,please see here.12345Next1926.57

PVC thin wall duct pipe is used for air / exhaust applications.The pipe is made with lightweight thin wall PVC and makes large jobs labor friendly because of its weight.Duct pipe is to be used only on open air systems and is not suited for liquid handling or pressure situations.PVC Duct pipe is rated to handle temperatures up to 140 degrees F.

Laboratory Exhaust Systems Simplified Lab Manager

Laboratory exhaust systems fall into three main classes chemical fume hoods for working with corrosive acids and bases,volatile solvents,and other hazardous chemicals; biological safety hoods,which can be designed to protect the work (clean air bench) or the worker (true biosafety cabinet); and standard exhaust hoods typically used in mechanical or machine shops or production areas.Laboratory Duct ConstructionFiberglass duct,linings,and flexible ducting should not be used because they may add particles to the air stream.Duct linings can also fail and clog ductwork.Flexible ducts may have an irregular surface that contributes to higher pressure-drops.In all cases,designers should choose duct material based on a careful analysis of exhaust Inspecting for Air Sealing at Kitchen and Bathroom Exhaust How Professionals Air Seal Holes Around the Kitchen Exhaust Duct.1.Openings for the duct should be cut that are no bigger than needed to fit the exhaust duct through the ceiling or top of the kitchen cabinet.Cuts should be clean and even.2.After the exhaust duct is installed,air seal with caulk between the duct and drywall from the room side.

Tapes and mastics used to seal metallic and flexible air ducts and flexible air connectors shall comply with UL 181B and shall be marked 181 B-FX for pressure-sensitive tape or 181 B-M for mastic.Duct connections to flanges of air distribution system equipment shall be sealed and mechanically fastened.Can I Use PVC Pipe for Air Heating Ducts? HunkerPVC is used for exhaust vents because it can handle the volume of forced exhaust,and the exhaust typically travels a direct route over short distances.An HVAC system for a home carries much larger quantities of air,and is piped from the basement throughout the home.Therefore the size of typical PVC is not suited for the task.Can I Use PVC Pipe for Air Heating Ducts?
