1. Rationale
ASTM C840 currently prohibits edge stacked gypsum panels on jobsites due to the hazard presented if panels are allowed to become unstable and fall. In many parts of the U.S., the standard has been ineffective at deterring companies from edge-stacking for multiple reasons. Regional and operational differences regarding the appropriate method to handle and store gypsum panels have failed to yield a consensus and as a result, accidents from falling gypsum panels continue. When a stack falls, injuries are often life changing, including documented incidents involving crushed limbs, amputations and even fatalities. The purpose of the proposed standard is to allow an alternative solution that will address these issues while maintaining a safe method to place and store gypsum panels on jobsites with a securing device to prevent incidental and accidental tip-over. Absent an alternate solution to the current standard, gypsum panels will likely continue to be delivered and leaned against walls without any means to secure the stack from tip over. The proposed standard addresses and mitigates the significant objections raised by companies who are presently non-compliant.
