Lubricant Storage

Lubricating oils and greases deteriorate with time like most of the material. Proper storage practice is to ensure sufficient stock turnover of the lubricants and their usage before any significant performance loss has occurred.

Conditions Affecting all Lubricants

The storage environment greatly affects the life of lubricants and greases. Conditions, which needs to be monitored, are: Temperature: Heat (greater than 45°C) and cold (less than 20°C) can affect lubricant stability. Heat increases the rate of oil oxidation, which may lead to formation of deposits and viscosity increase. Cold can result in wax and sediment formation. In addition, alternating exposure to heat and cold may result in drum breathing resulting in air being drawn into drums, which may result in moisture contamination. A temperature range of 20°C to 45°C is acceptable for storage of most lubricating oils and greases.

Light: Direct sunlight exposure may change the color and appearance of lubricants. Lubricants should be kept in their original metal or plastic containers and in shaded area.

Water: water may react with some lubricant additives, sometimes forming insoluble matter. Water can also cause microbial growth at the oil/water interface. Lubricants should always be stored in a dry location, preferably inside.

Airborne Contamination: drums and pails should not be stored in areas where there is a high level of airborne particles. This is especially important when a partially used container is stored. oxygen in athe air can react with lubricants and affect their viscosity and consistency. Keeping lubricant containers sealed until the product is needed is the best protection.

Condition Affecting Greases

Grease properties can change during storage depending on the type of thickener, its concentration, the base fluids, and the additives used. One condition that commonly affects greases is:

Oil Separation: oil will naturally separate from most greases. Temperatures in excess of 45°C can accelerate oil separation. If grease is removed from a drum or pail, the surface of the remaining grease should be smoothed evenly to prevent oil separation into the cavity.

Recommended Storage and Handling Practices for Lubricating Oils and Greases

Store lubricating oils and greases in a cool dry indoor area where airborne particles are at a minimum. Indoor storage also prevents deterioration of label and container from weather. The ideal storage temperature range is from 25°C to 30°C.

When necessary, bring grease to satisfactory dispensing temperature just prior to use.

If drums must be stored outside, use plastic covers or tip oil drums to direct water and contamination away from the bungs. Always store greases upright to prevent oil separation. Keep containers tightly covered or closed to avoid contamination.

  • Use clean tools and equipment when pumping or handling lubricants and greases
  • Rotate the inventory. Check the container manufacturing date and use the oldest container first.
  • Wipe off the tops and edges of containers before opening to avoid contamination.
  • Avoid skin contact especially used oil – Slight skin irritation
  • Take away from eye –
  • Avoid to breathing vapor or mists
  • Use oil impermeable gloves, Safety shoes, Goggles
  • Never put oily rags or tool into pockets

FIRST AID – TIPS

INGESTION

  • Do not induce vomiting (except for brake fluid)
  • Give milk or water (but not to unconscious persons)
  • Seek medical attention immediately
  • In case of Brake Fluid induce vomiting by depressing back of tongue

INHALATION

  • Remove patient to fresh air
  • Give artificial respiration if necessary
  • Seek medical attention immediately

EYES

  • Flush with water
  • For Brake Fluid seek medical attention immediately

SKIN

  • Wash with soap and water
  • Seek medical attention if irritation persists

Report any skin abnormality on any part of the body and seek medical advice without delay.
