1. Unless expressly provided otherwise or unless, in the opinion of the Administration having regard to the particular voyages on which the ship is constantly engaged, other requirements are appropriate, all life-saving appliances prescribed in this part shall:
a. be constructed with proper workmanship and materials;
b. not be damaged in stowage throughout the air temperature range -30° C to +65°C;
c. if they are likely to be immersed in seawater during their use, operate throughout the seawater temperature range -1°C to +30°C;
d. where applicable, be rot-proof, corrosion-resistant, and not be unduly affected by seawater, oil, or fungal attack;
e. Where exposed to sunlight, be resistant to deterioration;
f. be of a highly visible colour on all parts where this will assist detection;
g. be fitted with retro-reflective material where it will assist in the detection and in accordance with the recommendations of the Organization. ( applies to life-saving appliances on all ships)
h. if they are to be used in a seaway, be capable of satisfactory operation in that environment;
i. be clearly marked with approval information including the Administration which approved it, and any operational restrictions; and
j. where applicable, be provided with electrical short circuit protection to prevent damage or injury.
2. The Administration shall determine the period of acceptability of life-saving appliances which are subject to deterioration with age. Such life-saving appliances shall be marked with a means for determining their age or the date by which they must be replaced. Permanent marking with a date of expiry is the preferred method of establishing the period of acceptability. Batteries not marked with an expiration date may be used if they are replaced annually, or in the case of a secondary battery (accumulator), if the condition of the electrolyte can be readily checked.
