PART IV.-DISCUSSION
It is required by rule 102, section 10, that the basket of the extractor shall not be operated at a speed greater than the manufacturer's rating, which shall be stamped on the inside of the basket.
This is necessary because of the danger of centrifugal explosion when
operating the basket at a higher speed than that for which it was
originally built. The note appearing under (b) of this rule enables
the operator to move the basket by hand after the basket has been
Ettopped. This, of course, is to facilitate the even and easy loading
of the basket.
The guarding of the roll-type starching machine is not specified
in rule 110, a~ this type of machine does not appear to present a
point of operation hazard.
The hydraulic-plunger type of dampening machine is not mentioned in rule 120, as this type of machine does not appear to present
a point of OJ?Elration hazard.
The covermg of all steam pipes within seven (7) feet of floor or
working platform is required by rule 132, section 13. Contact with
hot steam pipes has caused many minor burns that have often resulted in infections. This rule does not specifically include steam
pipes directly under machines and which are not easily accessible.
The gradual opening of steam valves is required by rule 201. All
pressure vessels or chambers should be gradually warmed by allowmg only a small quantity Qf steam to enter the container at first.
A sudden rush of steam m a pressure chamber, such as an ironing
roll, causes unequal expansion which may result in an explosion.
It is advisable to install a separate clutch or other power controlling device on each floor where tra~ission shafting is used.
This will enable the machines on any floor to be stopped immediately
in case of accident without stopping the machines of any other floor.
