Dust Masks

Bromsgrove-based Harris make dust masks (more formally known as respirators) for protection against non-hazardous dusts. European standard EN149 defines various categories of dust mask - ranging from FFP1 which filters 80% of airborne particles, FFP2 which works at 94% of airborne particles to FFP3 at 99%. FFP1 is sufficient for paint dust, concrete/plaster and filler dust.

Drywall - also known as Plasterboard

Drywall is known by various names, including plasterboard, wallboard or gypsum board and is used for interior walls and ceilings. It became popular in the 1930s as a replacement for the lath and plaster approach (which actually has better sound proofing capabilities than plasterboard, but is more expensive to install).

Solvent Cement

Solvent cement is used for welding thermoplastic piping and sheets together, It does this by softening the material being bonded and forming a waterproof seal. The type of solvent cement must be compatible with the thermoplastic to form a strong bond.

Engine Oil

Engine oil, or motor oil, is a lubricant for internal combustion engines, found in cars and even lawnmowers.  The lubrication increases the efficiency of moving parts which move against each other. Lack of it increases fuel consumption and can lead to engine failure.

Rubbing of engine parts can lead to microscopic metallic parts deposited and circulated in the oil. Therefore an oil filter is often used to clean the oil.

Fog Lights

In fog, you should use fog lights due to limited visibility. They are designed for use in dangerously thick fog. They are completely separate units from regular lights.

Fog light beams are flat and wide, positioned low on the car. Their goal is to cut through fog and light up the road surface so drivers can see the road and stay in lane.

Fog lights are strong - so most places outlaw their use except in severe weather including thick fog. As soon as fog clears or mist dissipates drivers should turn off their fog lights.

Modern vehicles are typically equipped with front and rear fog lights.
