Abstract
A b s t r a c t The invention describes a gas-tight fully protective suit (2) which is worn in a polluted environment and protects the wearer against toxic substances. If combustible or explosive mixtures of gases and vapors are present in the surrounding air and are within the lower explosion limit and therefore constitute a risk of explosion, the wearer must be warned by being informed of the fact. To this end according to the invention, a measuring and alarm instrument (1) is disposed under the suit and comprises a diffusion measuring head (3) having active and inactive gas-detecting components. The diffusion-measuring head (3) is disposed in a gas-tight easing (5) in the suit material (2a), the easing being separated from the outer atmosphere by a diaphragm (12). The diffusion-measuring head (3) is connected by a cable (4) to the indicating and alarm instrument (1), which is secured to the wearer's body (Fig. 1).
Description
f ~016041 .
The Inventlon relates to a gas-tl~ht fully protectlve sult comprislng a measurln~ and alarm lnstrument worn under the sult for ~onltorlng ~n exploslve envrlonment, comprlslng a dlffuslon-measurln~ head havlng actlve and inactlve gas-detectlng components separated from atmosphere by a slntered dlsc.
Fully protectlve sults are worn for work ~nd rescue tn a polluted envlronment and protect the wearer from toxlc substances. If combustlble or exploslve mlxtures of ~ases and vapours are present ln the surroundln~ alr and are wlthln the lower exploslon llmlt and thus constltute a rlsh of exploslon, the wearer must be worned by belng Informed of the fact, vla a portable measurlng ond alarm Instrument. If the lnstrument ls worn outslde the protectlve sult, lt may be mode Inoperatlve by corroslve pollutants ln the surroundln~
olr. In addltlon, owlng to the awkward ~loves on the sult, the tnstrument will be dlfflcult to handle ond unrellable ln operatlon.
In addltlon, an acoustlc alarm outslde the sult may not be heard by : .

To thls end occordln6 to the lnventlon a ccsfng holdln~ the dlffuston-measurfin6 head of the meosurln~ and alarm tnstrument ls dlsposed tn gas-tlght manner tn the sult moterlal, the caslng beln~

The main advontages of the inventlon are that a dlffuslon-measurlng head of o measurlng ond olorm Instrument can be dlsposed by slmple meons in the protectlve sult wlthout the need for structural alteratlons to the suit.
Other advantageous feotures of the Inventlon wlll be clear from sub-clol~s 2 to 7.
