In case of the combined use of alloxime and atropine sulfate, potentiation of their antidotic effect is observed. Under the conditions of acute poisoning with trichlorfon, the index of protection (IP) amounts to 3.23 in rats. 

Efficacy of the anticonvulsant usage in antidotic formulas depends considerably on OPC type. Thus, index of protection (IP) for the composition of ChR (HI-6 inclusive), cholinolytics and diazepam is much higher for the treatment of intoxication with soman and tabun, than in poisonings with sarin and VX [93],... 

The destressed index of protected coal seam was obtained by actual measurement and the consistency of different indexes is good. Research findings show that extended destressed zone is located between the angles of theoretical destressed and normal projection of protective seam border fully destressed zone is within the limit of theoretic destressing angle by the contrast of numerical simulation and similar material test.

The Index of Protection is a code which gives us a means of specifying the suitability of equipment for the environmental conditions in which it will be used. 

The code is written as iP (index of Protection) foiiowed by two numbers XX. 

Zone 1 - water heaters, showers and shower pumps and SELV fixed equipment may be installed in zone 1. The electrical equipment must have at least IPX4 protection against water splashing from any direction. If the electrical equipment may be exposed to water jets from, for example, commercial cleaning equipment, then the electrical equipment must have IPX5 protection. (The Index of Protection codes were discussed earlier, and are shown in Fig. 3.74.)... 

Where a degree of protection is not specified, the number is replaced by an X which simply means that the degree of protection is not specified although some protection may be afforded. The X is used instead of 0 since 0 would indicate that no protection was given. The index of protection codes is shown in Fig. 13.3.

In selecting suitable equipment for such hazardous environments, reference should be made to the Index of Protection Ratings (IP Ratings) which is an internationally recognised system for classifying the degree of protection provided.
