Power Tools:- Verify that Safety Guards are fitted and operational Dust collection systems are operational when working the hazardous materials Abrasive Blast:- Ensure that following are installed and in working in order- - Dead man valve - Pressure control valves - Adequate moisture and oil separators - Protective clothing - Filtered and regulated air-supplied respirator - Entire system is grounded, including hoses, operator, and work piece - House couplings are wired shut - Abrasive hose is stored in a dry place - Nozzle is never pointed at human body or breakable object - Abrasive hose is inspected for damage and wear Dehumidification:- Dehumidification is defined as the removal of moisture vapor from the air to lower its dew point. Heating the air does not change its moisture content, which is a quantity of vapor, but it does improve its ability to hold more moisture vapor; and thus, it decreases its relative humidity. Cooling the air reduces the ability to hold moisture vapor and, thus increases its relative humidity. The temperature to which the air has been cooled enough to be saturated and capable of producing dew is called Dew point temperature. Most coatings cannot be applied successfully when the relative humidity is <90% because the solvent evaporation rate decreases at higher relative humidity and reaches zero evaporation rate at 100% relative humidity. This condition can result in solvent entrapment in the applied film, together with an impaired cure process, and is likely to cause subsequent coating failure in the form of blistering or severe peeling. The objective of dehumidification is to reduce the rate of corrosion to minimal levels by reducing the moisture content of the air to a safe level, 50% or less, at the prevailing temperature.

Dehumidification:-

Dehumidification is defined as the removal of moisture vapor from the air to lower its dew point.

Heating the air does not change its moisture content, which is a quantity of vapor, but it does improve its ability to hold more moisture vapor; and thus, it decreases its relative humidity. Cooling the air reduces the ability to hold moisture vapor and, thus increases its relative humidity.

The temperature to which the air has been cooled enough to be saturated and capable of producing dew is called Dew point temperature.

Most coatings cannot be applied successfully when the relative humidity is
