How Do I Work Safely with - Flammable and Combustible Liquids (General) An assessment of the specific ways flammable and combustible liquids are stored, handled, used and disposed of is the best way to find out if existing ventilation controls (and other hazard control methods) are adequate. Some workplaces may need a complete system of hoods and ducts to provide acceptable ventilation.

Flammable and Combustible Material Storage Safety Examples include butane, acetylene, methane and hydrogen. Flammable liquids are identified as liquids that have a flashpoint (minimum temperature needed for the liquid to produce a vapor with enough of a concentration to ignite) below 100 degrees Fahrenheit (F). There is an exception to this definition. If any of the components of the mixture have flashpoints of 100 deg. F or higher, then the material is classified as combustible rather than flammable. Another way to identify flammable liquids is by class. It is important to remember that with flammable liquids that it is the vapor coming off of the liquid that will ignite and burn, not necessarily the liquid itself.

- Definition and classification of flammable and combustible liquids are addressed in. Subsection 3.3.33 and Chapter 4 of NFPA 30. A flammable liquid is defined as a liquid. whose flash point does not exceed 100°F, when tested by closed‐cup test methods, while a combustible liquid is one whose flash point is 100°F or higher, also when tested. by closed‐cup methods. These broad groups are further classified as follows:

Duct (flow) A duct with less than 0.75 mg/100m 2 is considered to be clean, per the NADCA standard. A Hong Kong standard lists surface deposit limits of 1g/m 2 for supply and return ducts and 6g/m 2 for exhaust ducts, or a maximum deposit thickness of 60 µm in supply and return ducts, and 180 µm for exhaust ducts. duct with less than 0.75 mg/100m 2 is considered to be clean, per the NADCA standard.

Flammable & Combustible Liquids - Hazards Under the Workplace Hazardous Materials Information System (WHMIS) 1988, flammable liquids have a flashpoint below 37.8°C (100°F). Combustible liquids have a flashpoint at or above 37.8°C (100°F) and below 93.3°C (200°F). Flammable and combustible liquids are present in almost every workplace.

How to Line-Dry Clothes Indoors Cut down on the amount of laundry you have to do by wearing pants, skirts, and layering pieces more than once. Also, you might be more motivated to line-dry your clothes when you find out how much it costs to run a dryer. If you prefer to dry your clothes outside, learn how you can solve your outdoor line-drying problems. And whether you're line-drying your clothes indoors or outdoors, you can apply some simple trick to keep you line-dried clothes from getting stiff.

- The heating and cooling contractor should use proper materials when sealing ductwork-in particular, duct sealing mastic with embedded reinforcing mesh tape. To ensure ducts are tight, a home energy rater will conduct a duct leakage test, which is necessary to qualify for possible tax credits.

Dumb Ductwork Details According to the Dept. of Energy, leaky ductwork can easily diminish the efficiency of your HVAC system by 20%. Leaky ducts also allow “bad” air (air that you’d rather not be breathing) from crawl space, basement and attic areas to be drawn into the ductwork system and distributed throughout the house.

Thread: Clearance to Combustibles Re: Clearance to Combustibles I know this thread is a little old, but I called out lack of 1 clearance to a double wall water heater flue in a garage. The fire-rated drywall was installed right up against the flue. The plumber just called me and said that it was OK because the drywall was fire rated.

Sealing Ducts: Whatâs Better, Tape or Mastic? Gaps in ductwork or plenums that are over 1/16 or 1/8 inch wide can be sealed with mastic as long as the gap is first reinforced with fiberglass mesh tape. If you're using mastic to seal seams in fiberglass board ductwork, use fiberglass mesh tape for all joints.hoosing between tape and mastic. Since all duct-sealing products, including mastic and all types of duct tape, have disadvantages, deciding on the best duct-sealing strategy is tricky. Chuck Murray, an Energy Specialist with the Washington State University Energy Program, sees no reason to abandon mastic.

ASK THE INSPECTOR: Asbestos tape can be covered, left alone But health hazards usually only arise when the fibres become airborne, so asbestos-containing materials on your heating ducts should be a concern only if they are worn. Fortunately, you can probably deal with old tape on a few heating ducts in your basement in a cost-effective manner without professional help.

OSHAâs New Push on Combustible Dust and Lint â¦ and What Laundries Need to Know Essentially, OSHA is putting teeth to the National Fire Prevention Association (NFPA) standards last issued in 2006 in a systematic and rigorous way. OSHA is now required to look at combustible dust and lint issues even if the inspection is precipitated by other concerns (OSHA Directive CPL 03-00-008). The House passed its bill to enforce a new standard on combustible dust buildup for overhead and walls for all industries.
