The collection of oil samples from general plant.
|
|
| |
|
|
|
|
| |
1. |
|
Oil samples should be taken from a representative portion of the lubricant, and as
such the equipment being sampled should either be running or recently stopped. |
|
| |
|
|
|
|
| |
2. |
|
Access for obtaining samples may be through a specially designated sampling point,
filler caps, or occasionally from level plugs. Care must be taken not to allow spillages of the lubricant. |
|
| |
|
|
|
|
| |
3. |
|
The plant will be at working temperature, and care must be exercised as oil may be
hot enough to burn and scold. |
|
| |
|
|
|
|
| |
4. |
|
The sampler's bare skin should not be allowed to come into contact with the oil,
and sampling syringes, tubing and gloves should be used to prevent contamination of the skin. |
|
| |
|
|
|
|
| |
5. |
|
Vampire sampling syringes allow the sample bottle to be attached to the syringe,
and the oil to be drawn up through a length of tubing inserted into the oil. |
|
| |
|
|
|
|
| |
6. |
|
Conventional 'medical' type sampling syringes draw the oil up through a sample tube,
the oil is then ejected into a sample bottle. Care is needed handling the bottles, as the oil may be hot, and bottles
and tops may become difficult to handle with use. |
|
| |
|
|
|
|
| |
7. |
|
Samples must only be taken from chambers vented to atmosphere (unless specialist
equipment is being used to carry out pressurised sampling). If it is at all suspected that the oil chamber is under
pressure then the plant must be stopped, and the pressure allowed to dissipate before sampling proceeds. If in
doubt clarification must be sought from site personnel. |
|
| |
|
|
|
|
| |
8. |
|
Removal of guards to obtain samples must be carried out with the equipment isolated
and locked off, with a written permit or authorisation to work. |
|
| |
|
|
|
|
| |
9. |
|
Avoid contact of used oil with the skin, any spillages must be cleaned from the skin
at the earliest opportunity. |
