(DRMO). When this is not possible, the containers must be disposed of through a government-approved contractor or in a sanitary landfill approved by local government authorities.

Waste oils, filters, and contaminated fuel should be collected and disposed of properly. Most naval activities collect and dispose of waste oil periodically through a contractor who may burn it in a boiler plant or in a heating system. Naval supply fuel farms usually have the means to dispose of waste oils properly.

You will see contaminated water draining from the Equipment Operator's washrack every day. Work closely with the person in charge of the washrack to ensure that this wastewater is treated and not discharged into the storm sewer. Provisions must be made for pretreating or separating oil products and cleaning solvents used at the washrack.

Other than preventing oil pollution from vehicle and base equipment operation, Seabees are being considered for use in beach cleanup during major oil spill disasters. In case of a regional or national disaster from a major oil spill, this new manpower capability can be used very effectively by local commanders. A well-trained Seabee team can form the nucleus of a large-scale beach cleanup exercise team by using qualified personnel and heavy equipment.

AIR POLLUTION

You should be aware of the work conditions that cause air pollution and of the efforts required to reduce or correct the problem.

When incomplete combustion occurs in boilers, space heaters, and stoves, the unburned hydrocarbons and various other fuel components combine chemically to form by- products. Many of these by-products are harmful when emitted into the environment.

These by-products that affect the air are carbon monoxide, particulate matter, sulphur oxides, unburned hydrocarbons, nitrogen oxides, and lead. The most effective means of controlling air pollution from incomplete fuel combustion is to maintain the equipment properly and frequently. In this way, the equipment is operating at an optimal fuel and oxygen mixture. Another alternative, not always under your control, is to use only the best grade of fuel. This fuel contains low particulate matter, low water and sulphur content, and few contaminants.

ASBESTOS

Asbestos dust is another air pollutant that you must be knowledgeable of and concerned with in the installation, maintenance, and removal of asbestos material from a construction site.

Asbestos is a fibrous material that can be wooven like wool. Through a variety of processes, asbestos can be turned into thousands of construction products. Asbestos has been used by humans for over 2,500 years, It was not until the 1800s that asbestos was determined to be a health hazard. In the 1900s, asbestos was discovered to be the main cause of asbestosis (a generic term for a wide range of asbestos-related disorders) and mesothelioma. Mesothelioma at one time was a very rare form of lung cancer. It is presently occurring much more frequently among people exposed to asbestos dust particles
