Mass wasting represents a significant hazard in the region.
The inventory database of historic rock falls and other mass wasting events in Yosemite is extensive, dating back to 1857 (Stock et al., 2013).
In the Koro Toro fossiliferous area, KT 12 locality (16°00′N, 18°53′E) was the site of discovery of (Toumaï).
At both localities, the evolutive degree of the associated fossil mammal assemblages allowed a biochronological estimation of the hominid remains: early Pliocene (3–3.5 Ma) at KT 12 and late Miocene (≈7 Ma) at TM 266. This chronological constraint is an important cornerstone both for establishing the earliest stages of hominid evolution and for new calibrations of the molecular clock. Localities investigated in this area include TM 266 and TM 254 (Fig. The Kollé (KL), Kossom Bougoudi (KB), and Koro Toro (KT) fossiliferous areas were specifically studied to calibrate the authigenic Be dating method by direct comparison with biochronological estimations of co-located mammalian assemblages.
While OSHA’s overall record on worker health is undistinguished, it has seen periods of productivity.
The most notable came during the Carter administration in the late 1970s, when the agency rammed through standards for benzene, arsenic, lead, and other substances known to cause cancer, neurological problems, and other ailments.
It rarely uses the general duty clause to cite alleged health violations, having concluded that the burden of proof is too steep.
Hindered by court decisions, the White House, an often-hostile Congress, a weak underlying statute, and—some say —its own timidity, the agency is still searching for ways to protect workers from fumes, vapors, dusts, fibers, and liquids that can kill or incapacitate them.
OSHA has issued only 36 health standards and relies on mostly outdated exposure limits for the 470 substances it regulates; many more substances go unregulated.
Unions were influential then, government employees motivated.
“We had such loud, knowledgeable, vibrant voices,” said Eula Bingham, who ran OSHA from 1977 to 1981.
