Aluminum has always been used in various cooling systems, such as injection molding. Over the past several years however, the water treatment industry has seen even more use of the metal in heat exchangers and hot water boilers. The reason for this industry shift is the light weight, easy fabrication properties and excellent heat transfer characteristics of aluminum. The problem this presents is that aluminum doesn’t play very well with the traditional treatment chemistry used in closed systems. This week’s blog will review some of the basics with aluminum metallurgy and discuss some of the keys for treatment.

Legionella Update – How Would You Handle an Outbreak?
Posted by David Burroughs on Aug 19, 2015 2:20:00 PM
Back in June, QualiChem had a blog post on the approval of AHSRAE 188 which covered Legionella Risk Management Standards for the industry. With the recent legionella outbreaks in New York City and the fact that there generally are an increase in positive Legionella tests during the summer, we wanted to use this blog article to briefly discuss potential measures to take in response to a positive test in your cooling systems as well as share what the City of New York is doing in response to these outbreaks.

ASHRAE Standard 188P - Legionella Risk Management Update
Posted by David Burroughs on Jun 26, 2015 9:48:00 AM
Expected shortly will be an update from ASHRAE on the Standard 188 for Legionella Risk Management. This Standard has been a work in progress for many years and as the final comment periods come to close, we wanted to update as many people in the water treatment industry as possible. Please read below about this upcoming release.

OSHA will be implementing new hazardous chemical labeling requirements that update the current Hazard Communications Standards (HCS) to match the United Nations' Globally Harmonized System of Classification and Labeling of Chemicals (GHS). The existing OSHA standards enforce a performance-based requirement on chemical labels. This means that employers can choose how to convey the hazard information on a chemical label, allowing liberties to the manufacturer, importer, and distributor on how it is displayed. With the move towards GHS compliance requiring specific elements on the labels, many may feel uncertain of the required changes being made to the label format.
Let’s take a look at how GHS compliance will impact chemical labels for everyone.

As you're probably aware, like the United States, the Canadian government is making changes to chemical classification and workplace hazard communication to meet the requirements of the Globally Harmonized System (GHS) for the Classification and Labeling of Chemicals. The goal of these changes is to standardize and make international chemical trade more efficient.

The GHS Compliance Deadline is Drawing Closer, Are You Prepared?
Posted by David Burroughs on Feb 10, 2015 10:52:00 AM
In June of this year, GHS regulations will be implemented by OSHA that change the hazardcommunication standards for chemical classification and will impact labeling and Material Safety Data Sheets (MSDS). It’s critical that water treatment professionals understand the new standards and take appropriate actions in order to be compliant. Failure to do so will likely result in serious fines for business owners.
Are you prepared for the new changes as a result of GHS? Read on to learn more about what steps you need to take to ensure compliance and avoid penalties.

2013 Regulatory Requirements for GHS (What is GHS?)
The first set of requirements for complying with the Global Harmonized System, or GHS as it is known, are rapidly approaching later this year. GHS will require major changes to the hazard classifications of chemicals used in our market, along with major updates to MSDS’s and labels. This impacts any company that manufactures OR handles chemicals and will also bring a large cost of compliance as well.
