In some examples, a system includes an article of personal protective equipment (PPE) that includes a communication component; an industrial controller device that is configured to control an industrial device and includes a communication component; and a computing device communicatively coupled to the article of PPE and the industrial controller device, wherein the computing device is configured to: receive PPE data from the article of PPE and industrial controller data from the industrial controller device; determine, based at least in part on a set of the PPE data that temporally corresponds to a set of the industrial controller data, an occurrence of a safety event; and perform, based at least in part on the determination of the safety event, at least one operation.

Personal protective equipment safety system using contextual information from industrial control systems

A respiratory mask body defining a breathable air zone for a wearer and having a shut-off valve is provided. In an exemplary embodiment, the mask body includes one or more inlet ports configured to receive one or more breathing air source components. The shut-off valve is operable between a closed position and an open position, and when in a closed position the shut-off valve prevents fluid communication between the one or more inlet ports and the breathable air zone and the shut-off valve returns to an open position in the absence of an applied force.

Respirator negative pressure fit check devices and methods

A system includes at least one article of personal protective equipment, one or more industrial devices, an industrial controller device configured to output industrial controller data indicative of one or more attributes of the one or more industrial devices, and a computing device. The computing devices is configured to determine a set of one or more safety rules corresponding to a work environment at the first time and determine a change in an attribute of the one or more attributes of the one or more industrial devices. The computing device is further configured to identify an updated set of one or more worker safety rules corresponding to the work environment at the second time and determine whether the status of at least one article of personal protective equipment satisfies the updated set of one or more worker safety rules. The computing devices is further configured to perform at least one action based on determining whether the at least one article of personal protective equipment satisfies the updated set of one or more worker safety rules.

Dynamically determining safety equipment for dynamically changing environments

A method of fit testing includes providing a respirator; providing a sensor having a sensing element removably positioned substantially within an interior gas space of the respirator; providing a reader configured to be in wireless communication with the sensor; positioning the respirator over a mouth and a nose of a user while the sensor is positioned substantially within an interior gas space of the respirator; and observing respirator fit assessment data communicated from the sensor to the reader.

Fit-test method for respirator with sensing system

A buckle assembly for selectively connecting first and second straps of a personal protective device. The buckle assembly includes a receiver member and a latch member configured for coupling to a respective one of the straps. The receiver member defines a slot and provides a release arm. The latch member includes a latch tab pivotally connected to a base. In a latched state in which the latch member is disposed within the slot and a latch face is engaged with a capture surface. The release arm disposed over a portion of the latch tab. The latch face can be disengaged from the capture surface in response to an actuation force applied to the release arm. In some embodiments, the receiver member and the latch member incorporate various, complimentary guide surfaces that promote easy insertion of the latch member into the receiver member.
