Industrial exhaust ducts are pipe systems that connect hoods to industrial chimneys through other components of exhaust systems like fans, collectors, etc. Ducts are low-pressure pneumatic conveyors to convey dust, particles, shavings, fumes, or chemical hazardous components from air in the vicinity to a shop floor or any other specific locations like tanks, sanding machines, or laboratory hoods.
Labconco introduced the concept of a fume hood lined with fiberglass to improve durability and chemical resistance, [3] though from the 1990s onward, epoxy powder-coated steel, teflon and polypropylene coatings [8]: 169 were being recommended by literature for use in fume hood and exhaust construction. [10] [11]
A fume hood is an example of an engineering control that uses local exhaust ventilation combined with an enclosure to isolate a worker from nanomaterials that may become airborne. Engineering controls for nanomaterials are a set of hazard control methods and equipment for workers who interact with nanomaterials .
Nomex is a trademarked term for an inherently flame-resistant fabric with meta-aramid chemistry widely used for industrial applications and fire protection equipment. It was developed in the early 1960s by DuPont and first marketed in 1967. [1] The fabric is often combined with Kevlar to increase its resistance for breakage or tear.
The salt spray test (or salt fog test) is a standardized and popular corrosion test method, used to check corrosion resistance of materials and surface coatings.Usually, the materials to be tested are metallic (although stone, ceramics, and polymers may also be tested) and finished with a surface coating which is intended to provide a degree of corrosion protection to the underlying metal.
Vented balance safety enclosures are used in pharmaceutical, chemical, biological, and toxicological laboratories to provide maximum containment for weighing operations in weighing scales. Fume hoods, also known as laboratory chemical hoods, are one of the most important and widely used engineering controls to protect laboratory workers. Fume ...
