Cooperation is particularly requested in the proper use of protective equipment and the constant wearing of s monitoring films. It is further understood that the responsibility for policing (denying entrance to) and for granting, permission to enter regions designated as : unsafe will be taken only by the Project Director or hie authorized representatives. : Permission to enter th® unsafe region of contamination after the shot will be granted only by the "Going-in Board"i composed of Bainbridga, Hempelmann, and , The Site Monitoring Group will have four functions In connection with the "Qoing-ln Board" as follows: (1) To report to the Board the location and marking of safe limits of approach to the contaminated area} (2) To be advised of all personnel granted permission to enter the unsafe area and consequently to see that the personnel enter with proper protective and monitoring equipment} (3) To obtain from personnel upon leaving the unsafe area records of exposures received (meter readings, film badges, and nose swipe counts)} (U) To examine the personnel and equipment coming from, contaminated areas for advisable decontacdnation measures and to aid if necessary in such measures II.

capable of recording large exposures <. Protective clothing and respirators may be advised during certain operations ivith active material. In addition* persons handling active material vri.ll have hand and nose counts taken. Stationary red flags have bsen set up in advance around circular road and fire-breaks between 2003 and 3000 yards from zero. This area is expected to be -well beyond the danger from either alpha or gamma ground contamination after the shot. The flags are six feet hij-h and about $0 feet apart. They can easily be seen by people on foot, in cars* or on horseback. The flags will also act as windsocks for the initiated .rho may need- to approach the crater area. Besides the red flags there will be available twelve signs in English and Spanish warning inquisitive casuals that this is a dangerous area. These signs can be put up just before or just after the shot and will be placed at the six access points to the crater area marked in the appended diagram as 1* 2* 3» 5$ and 6. The flagged area and the access points may also serve as a preliminary clearance region during final assembly operations. 3« Clearance of Shot Area ' It is understood that the Head Monitor will be available to work with the Guard Captain* Lt» Bush, in clearing the area to the 10,000 yard shelters prior to the shot and In making the last check of preparedness at the shelters. B. Time of Shot ° Immediately Preceding & Following 1* Equipment available at 10*000 yard shelters (1) A respirator «r gas mask for each person. (2) Resistant film badge and regular pencil chamber for each person. (3) Coveralls for each person. (Ij) Telders filter for persons who may be where light flash is visible. (5) 7ehicl :s satisfactory for evacuation of all p ersonnel. (6) A vehicle for use of the monitoring technician and fc*P. to use in road survey and control. (7) A vehicle for th# use of boon's special monitors after other personnel have left the shelter. (8) Portable gamma meters - one for the monitoring technician on road surveys and one for the doctor when evacuating personnel. Should have sensitive as well as less sensitive (up to 1 r/hr) Instruments. (9) toe portable alpha meter. (10) One Filter Queen (11) At South Shelter - nose swipe and hand counting equipment. 2.

However, for perfect safety, all those who can perform their function at the shelter either inside or directly behind the shelter should ! be urged to do so. (b) There is insufficient knofledge cn the amount of light coming from the reaction and on the damage of brilliant flashes to the eye to pssrmlt the I Medical Group to recommend the safety of looking at ths original flash even j through a one to 5,000 reduction welder’s filter. Although the latter procedure i may be safe, the Medical Group will not take the responsibility for any ensuing ! eye damagec The recommended procedure for viewing the flash is to look in the I opposite direction until one sees the sky light up, turn around with the welder’s filter in front of the eyes, remove the filter only when the light looks pale. (c) If the alpha count in the air around the shelter by ’7attS4 portable proportional counter reaches 5 counts/mln, the personnel should be advised to put (d) If tile gamma intensity around the shelter approaches 1 r/hr, the doctors ! should advise iramediate evacuation from the shelter preceding away from zero.
