Sarin is dangerous through ingestion, inhalation, skin contact, or eye contact. The CDC recommends the following PPE."GENERAL INFORMATION: First Responders should use a NIOSH-certified Chemical, Biological, Radiological, Nuclear (CBRN) Self Contained Breathing Apparatus (SCBA) with a Level A protective suit when entering an area with an unknown contaminant or when entering an area where the concentration of the contaminant is unknown. Level A protection should be used until monitoring results confirm the contaminant and the concentration of the contaminant."
Contrast the above with the carefully stage managed photographs smeared all over the MSM of people wearing white paper coveralls, and photos of a supposed doctor busy tweeting with no PPE. Now today we finally have a few photos of people in bright yellow CBRN suits.
Seems to me the scriptwriters lost the plot for a while.
Also bear in mind their is an international conference on the future of Syria occurring very shortly. Is someone trying to stage manage the agenda
I detect more than a whiff of conspiracy behind all this seemingly contrived affair.
