Preparing Equipment and Instrumentation for Cold Weather Operations
As outdoor air temperatures drop, it is important for chemical and other facilities to be prepared for the unique safety challenges posed by cold weather, such as the hazards of water freezing and expanding, which can damage equipment or cause instrumentation to fail. When the temperature drops, the freezing process begins, and materials expand. This can crack or break pipes and rupture or damage process equipment. This damaged equipment may not become evident until the temperature rises, the ice thaws, and a leak develops. More subtle hazards may also exist, such as the formation of a hydrate, where water chemically combines with a compound, forming a solid that can also block process piping. This can happen even above freezing temperatures.

This digest summarizes three Chemical Safety Board investigations where ineffective freeze protection practices and programs were found to be causal to the incident. The document also provides the key safety lessons from these incidents, as well as additional freeze protection guidance and resources.

Bulging Hazardous Waste Drum Discovered in Waste Area
Waste drums have the potential to pressurize, particularly if they contain an unusual proportion of chemicals. Organizations using mixtures of Castrol Hysol AM and water in waste drums should take precautions against drum pressurization. During previous clean outs, buckets of water were used to clean out the wet separator. In the last clean out a hose was used to clean out the wet separator resulting in the use of more water than the past. It is speculated that the additional water used significantly changed the water to Hysol AM ratio enough that the diluted mixture produced gas.

Campus dorm evacuated after hazardous chemical substance discovered
WALTHAM, Mass. —
Over 175 students living in a Brandeis University campus dorm were evacuated after a hazardous chemical substance was found on campus.

The school said sodium cyanide was found on campus in the Foster Student Living Center, known to people on campus as "The Mods."

Waltham police and fire departments and a hazardous materials team responded to the scene and removed the chemical.

The school said there was no danger to the community and no one was hurt.

"Out of an abundance of caution, the 177 students who live in the Mods were evacuated; we anticipate students will be able to return very soon," the university said in a statement. "Waltham Police do not anticipate making any arrests related to this incident."

Congress considers US-wide furniture flammability standard
The US Senate has begun considering bipartisan legislation to adopt California's flammability standard for upholstered furniture nationwide.

Passage of the Safer Occupancy Furniture Flammability Act (S3551 or Soffa) would see California's 2013 Regulation, TB 117-2013, become the federal standard.

The US does not currently have a flammability standard for the products. In its absence, California's approach has served as the de facto national standard.

California updated its regulations five years ago to remove an 'open flame' test that manufacturers almost always met through the use of added flame retardants, which have been the subject of consumer concern in recent years for their potential to pose negative health effects. Following the state's action, many furniture companies moved away from using the substances.

For more than a decade, the US Consumer Products Safety Commission (CPSC) has been in a rulemaking process to consider a national mandatory flammability standard for upholstered furniture.
