How does a chemical detector tube work?
A sample of the atmosphere inside the compartment is drawn through a chemical reagent in a glass tube. The surface of the reagent becomes progressively discoloured as more contaminant vapour is detected in the sample. When this is read off the scale marked on the tube, the concentration of the vapour can be determined.
A sample of the gas from inside the compartment is sucked through a glass tube containing white cotton. As it does so, the gas becomes discoloured. The cotton will gradually dissolve and be replaced by the coloured gas, according to the concentration level. This may be read off a scale on the tube at the edge of the remaining cotton.
A sample of the air inside the compartment is pumped into a glass tube. As the pressure builds up inside the tube, a coloured stain can be observed, corresponding to the vapour pressure of the contaminant gas. The length of the stain corresponds to the percentage concentration of the gas.
The mositure in a sample of the atmosphere inside the compartment is allowed to soak into a strip of foam in a glass tube. This foam is impregnated with a reagent chemical. If it turns red, then the compartment is unsafe for entry; if it turns green, then entry is permitted.
Anyone who makes or permits a false entry to be made in the logbook shall be punished by imprisonment of up to 1 year according to:
The International Maritime Organization's Act of Maritime Activities
The Ship Safety and Security Act - Section 65.
Commissions of Inquiry of Maritime Activities

Some large slow speed diesel engines have jack bolt arrangements for retaining the main bearing top keep in place rather than the more conventional stud bolts. How does this arrangement affect the maintenance and checking procedures for the tie rods on the engine?

The tie rods should be fully tensioned before the jacking bolts are loaded to avoid overload of the bearing caps and frame structure.
The tie rods and jacking bolts must be tightened simultaneously to avoid excess load on either component.
