The present invention relates to a multifunctional transparent facemask system having a transparent facemask that seals over the nose, jawbone, and neck of a wearer to provide clean air for inhalation. The system filters out harmful contaminates from exhaled air before the exhaled air is released into the environment. The facemask system includes a removable visor to be disposed in front of the eyes of the wearer to prohibit drying of the eyes and preventing pathogens from entering therein. The system includes an air pump for providing fresh air to the facemask, an air filter for filtering out harmful contaminates from exhaled air, an inlet pipe for fresh air flow into the facemask, an outlet pipe for flowing exhaled air out from the facemask, and a small air tube for providing fresh air to the visor. The facemask includes a microphone and a speaker for providing effective communication, and LEDs for illumination.

Provided is a powered air blower unit for delivering air flow to a user with constant air flow or varying speeds of air flow. The air blower unit may also include a filter for purifying the air.

Disclosed is a welding shield that includes an air supply conduit for receiving and supplying ambient air into an internal portion of the welding shield, a sensor provided within the air supply conduit at an inlet of the conduit for detecting presence of one or more harmful gases in the ambient air, before the ambient air reaches the wearer for inhaling, and an alerting system operably coupled to the sensor for alerting the wearer upon detection of the one or more harmful gases in the ambient air.

Welding helmets, systems, and kits providing real-time fume exposure monitoring and warning capability during an arc welding process. A welding helmet configured to protect the head of a user during a welding process is configured with an intelligent warning apparatus and an air-sampling pick-up and output port. The air-sampling pickup and output port connects to a proximal end of an air sampling tube for sampling breathable air within the welding helmet, and a distal end of the air-sampling tube connects to an air-sampling in-take port of an external aerosol monitoring device. The intelligent warning apparatus communicates with the aerosol monitoring device to receive air sample output data from the aerosol monitoring device, and to process the air sample output data to generate warning data and/or warning signals based on preset exposure level set points and/or exposure warning operating modes.

A personal powered air respirator, for example a welding or spraying helmet (10), includes a remote controller (30) for adjusting one or more operating parameters of the helmet and a means of displaying information regarding said parameter in, on or adjacent the interior of the vision panel (12) of the helmet. The invention allows for convenient adjustment in use. The remote controller is adapted to clothing, such as belt, glove or pocket, or may be incorporated in equipment for use with the helmet.

Disclosed example respirators comprise: a filter configured to filter the air; a blower fan configured to provide continuous air flow at variable speeds; an air duct configured to direct air from the blower fan to an exhaust location, the blower fan configured to blow air through the air duct; and a blower controller configured to: control the blower fan to automatically adjust an airflow speed of the blower fan to a plurality of airflow speeds over a plurality of different time periods, the plurality of airflow speeds being within an airflow speed range.

An arc flash protective hood device. The protective hood is fitted with a passive blackbody radiation shield device formed with facing plates, each plate having a plurality of slots therethrough, the slots in one plate being in offset registration with the slots in the other plate, thereby creating a semi-tortuous path for fluid flow through the device. The semi-tortuous path for air flow is so formed to prevent arc-flash energy from passing through the shield device. Alternatively, the shield device may be a single, integral element, or each plate may be made in two or more segments. The blackbody radiation shield device may be mounted in an opening in a hood, and several such shield devices may be mounted in several openings in the hood.

In some examples, a system includes an article of personal protective equipment (PPE) comprising one or more sensors, the one or more sensors configured to generate usage data that is indicative of an operation of the article of PPE; and at least one computing device comprising a memory and one or more computer processors that: receive the usage data that is indicative of the operation of the article of PPE; apply the usage data to a safety learning model that predicts a likelihood of an occurrence of a safety event associated with the article of PPE based at least in part on previously generated usage data that corresponds to the safety event; and perform, based at least in part on predicting the likelihood of the occurrence of the safety event, at least one operation.

Air purifying respirator for user's having a face shield configured to shield the user's face from splatter, a head strap configured to encircle at least a portion of the users head, said head strap configured to support the face shield, at least one fan, and a fan housing positioned proximate an upper edge of the face shield, said fan housing configured to support said fan, a filter media positioned on an outer perimeter flange of the fan housing to maximizing a surface area of said filter media, a face shroud connected to a perimeter of the face shield, the face shroud configured to provide a seal between the face shield and the user's face and thus, to facilitate pulling the air through the filter media, and the fan pushes the filtered air from said fan housing to the user between said face shield and the user's face.
