Our Company

Global Safety First, LLC, (GSF) is a Pennsylvania limited liability company founded in early 2015 with the purpose of improving respiratory protection equipment for professionals and the general public. GSF develops, manufactures, and markets unique disposable safety masks and respirators (ReadiMasks), designed to substantially protect people from modern-day threats.

The ReadiMask was created to be virtually weightless, small enough to be carried at all times, and affordable for everyone. It is for use in (1) emergencies caused by accidents, terrorism, or natural disasters, (2) hospitals, medical offices, and other health care settings, (3) industrial settings, (4) the military, and (5) any environment where an individual is exposed, or may be exposed, to dangerous particulate contaminants.

The patented ReadiMask is a multipurpose respirator that substantially protects against airborne particles and is designed to fit both adults and children. It is the only full-face respirator that seals to your face using a hypoallergenic medical adhesive at the perimeter of the mask. Masks that apply with elastic straps or ties do not fit properly, allowing gaps around the edges of the mask where contaminants can enter, but ReadiMask’s medical adhesive creates a tight seal that enables the filter and eyeshield to provide substantial protection. The ReadiMask is pocket-sized, virtually weightless, and available with or without the eyeshield.

Our Team

Brian K. Weller, Chief Executive Officer, Global Safety First, LLC


Brian Weller is the Chief Executive Officer for Global Safety First, LLC, and is responsible for the overall operations and management of the company. Weller is a skilled entrepreneur with a long-standing commitment to safety. His mission for GSF is to find or create products that his team can take from patent to the end user, and in that process, ensure that it becomes the best product that it can be.

Previously, Weller owned and operated successful insurance property-damage restoration companies in four states. In addition, he became an expert witness in state and federal courts for property-loss damage assessment and subrogation valuations. He also provided legal defense services for property and subrogation cases for insurance carriers.

In 2003, Weller purchased a newly developed fire safety product, had the product patented, raised the necessary capital, developed and distributed the product, and achieved ten-percent market penetration before selling it to a public company.

In 2015, Weller and his team formed GSF to provide a vehicle to search for unique products that could help save lives. ReadiMask is the first acquisition in what is hoped to be one of many products that will protect consumers as well as individuals who put their lives on the line to protect others.

Weller has a B.A. in history from Gettysburg College and a J.D. from Widener University School of Law. He was admitted to the Pennsylvania Bar in 1987.

“Our company goal is to become profitable so that a portion of those profits can be donated to organizations that support the people who dedicate their lives to the safety of others.” – Brian Weller, CEO, Global Safety First
