Occupational safety and health culture, or more briefly 'OSH culture', is a complex concept that has. been the subject of extensive research since the eighties. There are different perspectives on how to. define and approach this OSH culture in organisations.
In plumbing, a trap is a device which has a shape that uses a bending path to capture water to prevent sewer gases from entering buildings, while allowing waste to pass through. In refinery applications, traps are used to prevent hydrocarbons and other dangerous gases from escaping outside through drains. In domestic applications, traps are typically U, S, Q or J-shaped pipe located below or within a plumbing fixture. An S-shaped trap is also known as an S-bend. It was invented by Alexander Cumm
Vents admit air into the pipes that helps equalize the air pressure in the pipes to prevent blowback and siphoning of the water seal in the trap. The trap. All fixtures need one, and only one, trap that is set level. Fixtures with an internal trap, like a toilet, do not need and should not have a separate trap. One trap provides the water seal to keep out sewer gas. Two or more traps impede flow and are more likely to become clogged.
