MSA EMERGING MARKETS: MEXICO MEXICO h In Mexico, Confined Space Expertise Helps  Protect Steel Workers While not o ffi cially on MSA’s list of emerging markets,  Mexico fits that bill in many ways for our North America  business segment. With the tari ff  eliminations of NAFTA  and geographic continuity with the balance of North  America, Mexico is experiencing dramatic growth in  its manufacturing sector. In fact, MSA was just one of  many American and Canadian companies to build new  manufacturing facilities in the country in recent years, with our state-of-the-art 77,000 square foot plant (shown  above) opening in Querétaro in late 2007.  With Mexico’s expanding industrial base comes an  increased need for safety equipment for workers. One of the many customers served by MSA Mexico in 2011 was  steel producer ArcelorMittal, whose 4 million tons per  annum facility in the port city of Lázaro Cárdenas makes it the largest manufacturer of steel in the country.  MSA has long served ArcelorMittal facilities in the U.S.  and Europe, but this was our first opportunity to do so  in Mexico. The driver: the launch of the facility’s confined  space entry program.  Large industrial facilities often have a large number of  confined space environments. Accordingly, there is a  need to keep workers safe in any eventuality. This means  a need for products representing four of MSA’s five Core  Product groups – Industrial Head Protection, Supplied-Air  Respiratory Protection, Portable Gas Detection, and Fall  Protection as workers, for example, descend steep ladders  into below-ground confined spaces.  And, perhaps just as importantly, it means training workers and sta ff  not only in the proper use of each piece of equipment, but also in safe practices while performing work in any kind of confined space to ensure full  compliance with all applicable standards.  MSA provides expertise in all of these areas, and our ability  to provide outstanding training and confined space audits,  alongside state-of-the-art products, won us ArcelorMittal  Lázaro Cárdenas’ business in 2011. It is the kind of value-  added service that is helping MSA gain new business in  Mexico, as well as in other markets throughout the world. MSA’s value-added expertise  continues to earn new business  around the world. In 2011,  MSA’s confined space training  program helped win business  from ArcelorMittal. Shown at  left is an on-site confined space  training session conducted by  MSA Mexico. MSA 2011 ANNUAL REPORT 9
