After an Unfortunate Incident USPS New Rules are Being Created<\/h2>\n

It was a normal day at the Westgate Post Office, on the outskirts of Rochester, NY. Then a strange odor filled the air, irritating people’s eyes and respiratory passages. By the time the emergency crew had finished its investigation, six people had been sent to hospital for observation, and ten more had been evacuated. At last the culprit was discovered, lurking in an innocuous-seeming package. It turned out that a bottle of nail polish remover inside had broken and the liquid was dripping from the box.<\/p>\n

Luckily, no one was seriously hurt. “This was unfortunate, but it could have been worse<\/em>,” said Karen Mazurkiewicz, spokesperson for the U.S. Postal Service (USPS). It isn\u2019t actually illegal for people to ship small amounts of hazardous materials through the mail in the U.S., as long as shippers comply with the “Hazardous Materials Regulations” of Title 49, Code of Federal Regulations<\/em> (49 CFR), as well as the “Postal Service Regulations” in Title 39 of the Code (39 CFR). Guidelines for mailing hazardous materials can be found in USPS Publication 52 \u2013 Hazardous, Restricted and Perishable Mail<\/em><\/a>.<\/p>\n

Unfortunately, many shippers in private life (and even some in industry) aren\u2019t even aware that these regulations exist. And what was created by the U.S. Department of Transportation (DOT) for commercial shippers may not provide workers and customers of the USPS the protection they need when exposed to shipments from the general public.<\/p>\n

Much of the battle to improve hazmat safety in the mail lies in improving hazmat awareness. Most people aren\u2019t aware that many consumer products, such as the nail polish remover in Westgate, are classed as hazardous materials. But another part of the problem lies with the lack of guidance given in 49 CFR for packaging these very small amounts.<\/p>\n

Of course, even non-hazardous substances can be a problem in the mail. For example, a spill of water-based paint may not be a fire or health hazard, but can destroy other mail, and require expensive clean-up. The USPS has noted that:<\/p>\n

“The Postal Service and United States Postal Inspection Service (USPIS) have observed an increased frequency of incidents involving containers of liquids rupturing while in Postal Service networks. A typical result of these incidents is damage to surrounding mailpieces and to Postal Service equipment.<\/em>“<\/p><\/blockquote>\n

USPS will accept many hazmat items as “Limited Quantities” (or its soon-to-be-obsolete, cousin, “Consumer Commodities”). This method of shipping does not require packaging specifically certified for hazardous materials, instead giving maximum sizes for inner packagings, which should be enclosed in “strong outer packaging,” not exceeding 30 kilograms (66 pounds). Commercial shippers usually have a good understanding of what a \u201cstrong outer packaging\u201d would entail, having experience with the conditions a package in transport may be exposed to.<\/p>\n

However, the general public may not know exactly what happens to a package during transportation. Designing a package that is lightweight yet resistant to transport conditions requires an understanding of these conditions, as well as the way packaging functions. Consumers may end up selecting inadequate packaging, which leads, inevitably, to situations such as the Westgate spill. The USPS has noted plastic containers are a particular problem, since many shippers believe them to be stronger and more impact-resistant than they actually are.<\/p>\n

USPS Proposes Changes<\/h3>\n

To improve safety for both USPS workers and the public, USPS has proposed to modify 39 CFR by giving more specifications for the packaging of liquids in the mail, whether they are hazardous or not. This Notice of Proposed Rulemaking (NPRM) was published on Monday, July 9, 2018 in the Federal Gazette<\/em>.<\/p>\n

The proposal will require\u00a0liquids to be\u00a0packaged in\u00a0\u201ctriple packaging.\u201d This consists of the inner containers that hold the liquid, placed inside a sealed, liquid-tight secondary packaging, before being placed inside the outer packaging, such as a box. Plastic bags would be acceptable as secondary packagings. Absorbent and cushioning material must be placed inside the secondary packagings to protect the inner containers and soak up any escaping liquid in case of damage.\u00a0 (Those who ship using the \u201csmall quantity exception\u201d of 49 CFR \u00a7173.4 or as \u201cexcepted quantities\u201d under the IATA Dangerous Goods Regulations<\/em> <\/a>will find the packaging design requirements familiar.)<\/p>\n

Screw caps must have threads with at least one and a half turns. Other means of ensuring a safe closure can involve clips, soldering or \u201csimilar means.\u201d<\/p>\n

Packagings of liquids must also be marked as follows:<\/strong><\/p>\n

\u201cMailers must mark the outer container of a mailpiece containing liquid to indicate the nature of the contents, and include orientation arrows in accordance with Publication 52, section 226.<\/em>\u201d<\/p><\/blockquote>\n

Another part of the NPRM includes language to \u201cencourage\u201d the use of locking rings when mailing metal containers whose lids are held on by friction only (such as paint cans). These lids, unless secured, can easily come loose during transport. The proposal will only recommend these closures, not make them mandatory at this time, but if the rings aren’t used, other methods of creating a secure seal such as paint can clips must be used.<\/p>\n

If you have comments on this proposed change, you can e-mail them to ProductClassification@usps.gov<\/a> with a subject line of “New Standards for Liquids.” If you prefer regular mail, address comments to The Manager, Product Classification, U.S. Postal Service, 475 L\u2019Enfant Plaza SW, Room 4446, Washington, DC 20260-5015. Comments will be accepted until August 8, 2018.<\/p>\n

USPS says that if this proposed rule is adopted, they will further work to the Mailing Standards of the United States Postal Service, Domestic Mail Manual (DMM)<\/em><\/a> and Publication 52<\/em> to clarify and harmonize language in on shipping liquids to the new rule in 39 CFR. They also intend to add clarifying language regarding the use of orientation arrows to ensure that liquids are always carried with their openings upright.<\/p>\n

The Final Rule based on this Notice of Proposed Rulemaking has been published on March 18, 2019, to update Publication 52 for packaging liquid hazardous materials. The Final Rule, and a summary of comments and response, can be found here.<\/a><\/span><\/span>\u00a0<\/span><\/span><\/p>\n
