Ammonia also disperses easily, since is lighter than air (its density is 60% that of air), and does not settle in low lying areas the way hydrogen sulfide and other dense odorous compounds do. These factors make ammonia odors more prevalent on-site than off-site.
Toyota started phasing EDRâs into certain of its vehicles in 2001, and all vehicles from the 2007. model year forward are equipped with these devices. [4] While the large majority of Toyota and. Lexus vehicles have EDRâs equipped to record both pre-crash and crash-phase data, several. models have units that do not capture any pre-crash data. By the end of 2010, all newly-. manufactured Toyota and Lexus vehicles were equipped with EDRâs that record both pre-crash. and crash-phase data.
