Consumable Lubricant, grease, Oil and Chemical for Electrical Plants

All lubricants proposed for the works should be suitable for all operating and environmental conditions that will be met on site.
All oils and greases should where possible be readily available in the country of installation.

The number of oils and greases should be kept to a minimum and the Service-provider should submit to the Engineer for approval a schedule containing all items of the works, which require lubrication together with the quantity type and grade of lubricants required.

The Service-provider should supply the first fill of lubricants for all plant supplied under the requirement and any addition up to the final date arising from the reliability trial and previous operation.

The Service-provider should provide to the Employer at the issue of the taking over certification for each section of the works sufficient flushing oils, lubricants and greases necessary for efficiency operating and maintaining the plant at full load 24 hours per day for a period of 12 months.

Lubricant Storage and Handling for Construction Plant

Considering the consumption rate storage lubricant packages may different forms like- pails (20 liters), drums (200 liters), totes (1600 liters) and bulk tanks. To select the suitable package you need to analysis of the past history considering:
  1. Historical average consumption rate;
  2. Refill emergency and delivery delay;
  3. Delivery standard time;
  4. Delivery delay risk considering natural and man-made causes;
  5. Storage facility in store;
  6. Storing life time of the product; etc.
The lubricant storage compound may depend upon their hazardous characteristics. For lubricant compound or storage building may consider the following points:


  1. Access for delivery, transfer and emergency period;
  2. How minimize the risk to nearby premises on & off site in a fire;
  3. Fire proof construction;
  4. Distance from electrical structure/equipment;
  5. Distance from explosive/hazardous substances;
  6. Safe distance from any substances;
  7. Well ventilated and lighted are;
  8. Well equipped for fire detection and protection; etc.
It’s important that storage life of lubricant depends on varying temperature and humid environment. Extreme hot or cool environment may cause of chemical degradation; so storage building temperature conditioning is necessary to keep the chemical in good.

Similarly, hydroscopic petroleum chemical when exposed to humid air they absorbed moisture. Moisture immediately degrade the chemical properties.

So, there is very much chance at site storage in a construction plant to degrade the chemical if not taken extra care about it, due to temperature and humidity, because not always possible to arrange proper store due to environmental, financial or space constraints.

Transportation of Chemical

Transportation of lubricant or any chemical should be under especial regulation comprising local and international codes. Transport may be by road, rail, sea or air; but everywhere should be follow following requirements:

  1. detail documentation;
  2. classification and packaging each item and marking properly;
  3. suitable container and its examination & testing properly;
  4. details information like duties of consignors, operators, drivers, etc.;
  5. adequate warning labels to be displayed on containers, tanks, and wagons;
  6. information regarding loading and unloading procedure;
  7. training of crews/drivers and others who will handle the goods;
  8. security and safety measures for any emergency situation;
  9. especial requirements if required.
All kind of lubricant and chemical handling and storing details are described in particular materials MSDS (Material Safety Data Sheet) that should be available in storage area in a dedicated way. Regarding MSDS there is a complete post where a list of website denoted for finding MSDS in online MSDS & HAZARDOUS CHEMICAL MATERIAL HANDLING AND STORING

Personal Protection & Chemical Handling

Must consider the wearing PPE (Personal Protective Equipment) in general working time and chemical handling time is not same hazard risk. Occasionally, personal protection may be the only practicable measure and a legal requirement, but keep in mind sometime really necessary to protect the life! So, project engineer must ensure the personal protection at site during execute the project site works; and ensure supply sufficient PPE.

Chemicals and other Consumable

The require chemicals and consumable includes for the provision of all chemicals, resins, and other consumables required for testing, commissioning and setting to work of each section of the works.

The Service-provider should provide all such chemicals and other consumables required for the efficient operation and maintenance of the plant at full load 24 hours per day for a period of 12 months for each section of the works from the date of the final certificate.

The Service-provider should prepare a list of these consumables giving quantities necessary for each section of the works and the recommended suppliers.
