Abstract

An airborne hazard detector including a housing having a slot in a side thereof for receiving a sheet of M8 chemical detection paper and a principal opening in the top thereof for the passage of airbourne chemical warfare agents to the sheet and for observing color changes in the sheet. The housing also has a number of secondary openings adjacent the principal opening. A number of manually rotatable dials is positioned within the housing with each being visible through one of the secondary openings. The dials bear indicia indicative of the time and date that the sheet of M8 chemical detection paper was last inspected.

Claims

1. An airborne hazard detector, comprising:

a housing having a slot in a side thereof for receiving a sheet of M8 chemical detection paper and a principal opening in the top thereof for the passage of airborne chemical warfare agents to the sheet and for observing color changes in the sheet, said housing also having a plurality of secondary openings adjacent said principal opening; and

,

a plurality of manually rotatable dials each being positioned within one of said secondary openings, said dials bearing indicia indicative of the time and date that the sheet of M8 chemical detection paper was last inspected, said indicia being visible through said secondary openings.

2. The airborne hazard detector according to claim 1 further comprising a sheet of M8 chemical detection paper positioned within said slot.

3. An airborne hazard detector, comprising:

a housing having a slot in a side thereof for receiving a sheet of M8 chemical detection paper and a principal opening in the top thereof for the passage of airborne chemical warfare agents to the sheet and for observing color changes in the sheet, said housing also having a plurality of secondary openings adjacent said principal opening and an aperture in its bottom;

a plurality of manually rotatable dials each being positioned within one of said secondary openings, said dials bearing indicia indicative of the time and date that the sheet of M8 chemical detection paper was last inspected, said indicia being visible through said secondary openings; and

,

a post being selectively inserted within said aperture for supporting said housing above the ground.

4. The airborne hazard detector according to claim 3 further comprising a sheet of M8 chemical detection paper positioned within said slot.

5. The airborne hazard detector according to claim 3 further comprising a cap releasably fitted over said housing to close said slot.

6. An airborne hazard detector, comprising:

a housing having a slot in a side thereof for receiving a sheet of M8 chemical detection paper and a principal opening in the top thereof for the passage of airborne chemical warfare agents to the sheet and for observing color changes in the sheet, said housing also having a plurality of secondary openings adjacent said principal opening as well as a first aperture in its bottom and a second aperture opposite said slot;

a plurality of manually rotatable dials each being positioned within one of said secondary openings, said dials bearing indicia indicative of the time and date that the sheet of M8 chemical detection paper was last inspected, said indicia being visible through said secondary openings; and

,

a post having a blunt end and a pointed end, said blunt end being capable of selective insertion into said first aperture for supporting said housing above the ground and said pointed end being capable of selective insertion into said second aperture for storing said post.

7. The airborne hazard detector according to claim 6 further comprising a sheet of M8 chemical detection paper positioned within said slot.

8. The airborne hazard detector according to claim 7 further comprising a cap releasably fitted over said housing to close said slot and prevent the loss of the sheet of M8 chemical detection paper positioned within said slot.
