• STATIC EQUIPMENT• Comply with FMA Regulation (CF Requirement).• More concentrate in prevention and any modification
must obtained the approval from DOSH.

• FMA = Factories Machinery Act.
• Moving part.• Design and specification (head, types of fluid, capacity).• Operating condition (pressure, noise, vibration,
lubrication, mechanical seal, belting, roller, alignment, cooling system).
• Efficiency of the equipment.

• Reactor• Equipment for reaction take part.• Main equipment to produce the product.
• Boilers• Boilers are fuel-burning appliances that produce either hot water or
steam that gets circulated through piping for heating or process uses.• Proper maintenance and operation of boilers systems is important with
regard to efficiency and reliability.– Fire-tube Boiler– Water-tube Boiler– Electric Boiler

• A cooling tower is a specialized heat exchanger in which two fluids (air and water) are brought into direct contact with each other to affect the transfer of heat.
• In a “spray-filled” tower, this is accomplished by spraying a flowing mass of water into a rain-like pattern, through which an upward moving mass flow of cool air is induced by the action of a fan
• Cooling Tower

• Used to transfer liquid form one location to another. • Centrifugal pumps basically consist of a stationary pump
casing and an impeller mounted on a rotating shaft.• The pump casing provides a pressure boundary for the
pump and contains channels to properly direct the suction and discharge flow.
• The pump casing has suction and discharge penetrations for the main flow path of the pump and normally has a small drain and vent fittings to remove gases trapped in the pump casing or to drain the pump casing for maintenance.
• Pump

• COMPRESSORS• It runs tools and machinery, provides power for
material handling systems, and ensures clean, breathable air in contaminated environments.
• A plant’s expense for its compressed air is often thought of only in terms of the cost of the equipment.
• Energy costs, however, represent as much as 70% of the total expense in producing compressed air.

4. LUBRICATION
• Use as lubricant between same or different type of material that is in contact to each others
• Application; plug valve, gland packing, mechanical seal, bearing and etc• Present in gas or liquid or solid form• Reason; protection to the equipments, parts in order to sustain
production, minimize downtime and maintenance cost
• Reduced friction & power requirement (bearing, plug valve)• Reduced wear• Heat Dissipation• Rust & Corrosion Prevention• Prevent Contamination & Solid Deposition
