For over 30 years, Safety Environmental Control, Inc. (or, simply, “SECI”) has been the trusted source of contractors, government agencies, and supply houses across the United States and Canada for unbeatable prices on environmental safety and personal protective equipment and supplies. 



Founded in Keene, New Hampshire in 1988, SECI started as a small, but uniquely driven wholesaler/broker of environmental safety equipment and supplies for the abatement and remediation industry.  From the outset, the goal was simple – help fellow distributors and safety supply houses across the United States and Canada become more profitable by providing a dependable and on demand supply of the products they needed at prices not found elsewhere.  Successful in that goal, SECI quickly became the best kept secret in the industry, providing unbeatable pricing with an unmatched commitment and dedication to customer service.  And, as the busines continued to grow and the secret got out, SECI expanded its product offerings to include industrial safety products and supplies, personal protective equipment (PPE) and disaster response supplies, all at the exceptionally low prices the company has become known for.   Continuously adding onto its fiercely loyal customer base and following, SECI has since opened three branches in California (Safety Environmental Control of California, Inc.), Massachusetts (Safety Environmental Control of Massachusetts, Inc.), and Maryland (MMI Industrial Sales) focused on delivering the same supreme prices and excellent customer service to the end user market.

Refusing to take the path that several of its industry foes have taken over the years, SECI remains privately and family owned and not beholden to investors or private equity firms.  The foregoing has allowed us to maintain steady growth while refusing to sacrifice what made that growth possible in the first place – providing excellent customer service and unbeatable value to our customers.

We remain steadfast in our commitment to providing exceptional value and service to the abatement, remediation, industrial, and construction industries. But, that is not where our capabilities end.  We have also become the trusted resource of government, healthcare, first responders and relief workers at home and abroad in ordinary times, as well as in times of emergency and peril.  SECI was the primary go to for the Port Authority of New York and New Jersey in the wake of the 2001 World Trade Center attacks for essential personal protective equipment, disaster response supplies and environmental safety equipment and supplies. In 2005, SECI provided similar essential equipment and supplies in the Hurricane Katrina relief efforts.  In 2010, SECI was there once again providing necessary relief and response equipment in the fallout and cleanup of the BP oil spill disaster.  No stranger to pandemics and similar health emergencies following the SARS and H1N1 outbreaks, SECI is now on the forefront of those companies providing essential workers with the PPE and environmental and safety equipment and supplies they need in the ongoing and tireless fight against the coronavirus pandemic.



The backbone of SECI and its three branches is the close network of dedicated employees it has compiled over several successful decades. Each employee is committed to one thing and one thing only – meeting and exceeding the needs of our customers.  The customer has been, and always will be, our top priority.  To that end, we unequivocally promise to work tirelessly towards building and maintaining successful, long-lasting, and meaningful relationships with each customer we have the fortunate opportunity of serving.  We also promise to continue our longstanding practice of providing honest, straightforward pricing and extending every little last piece of savings we can to each customer. When you call, email or purchase via the website, you become one of our valued and respected customers – you are not just a number and we promise not to treat you as such as we work toward exceeding your expectations!



With the 2020 launch of our new and improved website, SECI is excited to bring its vast product inventory and savings to customers and end users worldwide.

Please note that inventory is being added daily to the website, and we appreciate your patience as we bring your favorite products to your fingertips. If any time you do not see what you are looking for, please just contact us - we may have what you need in one of our warehouses or we will gladly get it to you!  Additionally, if you see an in-stock product listed elsewhere at a lower retail price, just let us know, and we will do everything that we can to offer you a better price!  Currently, all website sales are processed out of our New Hampshire location.  Scheduled warehouse pickups are available exclusively at our New Hampshire location Monday thru Friday, 9 a.m. to 5 p.m. EST.  United Parcel Service (UPS) picks up outgoing packages by 5:00 pm M-F, enabling online orders that are shipping via UPS to go out the same day if possible!  The SECI delivery truck operates M-F for large volume orders to nearby customers. If you would like to discuss delivery options, please call to speak to a team member.
