About this capture
Organization: Internet Archive
These crawls are part of an effort to archive pages as they are created and archive the pages that they refer to. That way, as the pages that are referenced are changed or taken from the web, a link to the version that was live when the page was written will be preserved.
Then the Internet Archive hopes that references to these archived pages will be put in place of a link that would be otherwise be broken, or a companion link to allow people to see what was originally intended by a page's authors.
The goal is to fix all broken links on the web. Crawls of supported "No More 404" sites. Collection: GDELT A daily crawl of more than 200,000 home pages of news sites, including the pages linked from those home pages.

ICSC: 0240 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994. No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and NIOSH IDLH values.
PHYSICAL STATE; APPEARANCE:
RED POWDER, TURNS GREEN ON EXPOSURE TO MOIST AIR.
Shock-sensitive compounds are formed with acetylenic compounds, ethylene oxides and azides. Reacts with strong oxidants like chlorates, bromates and iodates, causing explosion hazard.
OCCUPATIONAL EXPOSURE LIMITS:
TLV: (Fume) 0.2 mg/m3; TLV: (Dusts & mists as Cu) 1 mg/m3 (ACGIH 2007).
MAK: 0.1 mg/m3 (Inhalable fraction)
Peak limitation category: II(2) Pregnancy risk group: C
OSHA PEL*: TWA 1 mg/m3 *Note: The PEL also applies to other copper compounds (as Cu) except copper fume.
NIOSH REL*: TWA 1 mg/m3 *Note: The REL also applies to other copper compounds (as Cu) except Copper fume.
NIOSH IDLH: 100 mg/m3 (as Cu) See: 7440508
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation and by ingestion.
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.
EFFECTS OF SHORT-TERM EXPOSURE:
Inhalation of fumes may cause metal fume fever. See Notes.
EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization.
Boiling point: 2595°C
Melting point: 1083°C
Relative density (water = 1): 8.9
Solubility in water:
N O T E SThe symptoms of metal fume fever do not become manifest until several hours. Card has been partially updated in January 2008: see Occupational Exposure Limits.
