In one sentence, describe what the following article is about: If you are new to a work environment, you can learn a lot by watching other employees work, particularly those who have worked many years in the same industry. Observe what kind of care they take to avoid contact with allergens, or, in some cases, learn what not to do by seeing the risks they take. Before exposing yourself, you can see if their skin comes into contact with a substance; then decide for yourself if you want to modify the process, substitute a substance (if allowed), or use additional personal protective equipment. If you suspect contact dermatitis or are worried about exposure to a substance, do what you can to eliminate that substance from your work environment or minimize your contact with it. In most cases your employer should have procedures in place your contact with harmful substances, such as those put in place through the Occupational Safety and Health Administration. If you or your employer are unable to eliminate the allergen or harmful agent altogether, steps should be taken to adjust your work environment or isolate the hazard from the workers. The following are options of measures that can be taken: Technical measures. Adapting technical procedures that can isolate the agent, such as encasing the harmful agent in another substance or tunneling the harmful agent through an exhaust fan. Organizational measures. In some workplaces, only qualified employees (or those who have shown competence to work around a specific agent) are allowed to perform specific tasks in the workplace. This minimizes the potential risk of exposure for other employees in the workplace. Personal measures. In some cases, simply increasing the amount of personal protective equipment (known as "PPE") that employees are required to wear can minimize exposure to the allergen. For example, a face mask can minimize an employee's exposure to harmful vapors or fumes from a harmful agent. If you are concerned about your exposure to certain pathogens in your workplace, speak to you boss or supervisor immediately. Your boss or supervisor should be acquainted with the particular hazard, and can provide specific information and protocol regarding exposure. Workplace safety is regulated and monitored through the Department of Labor (DOL) and the Occupational Safety and Health Act (OSHA); your employer has a responsibility (and in most cases, is federally mandated) to maintain a safe and healthy workplace. Most employers in the nation come under the jurisdiction of OSHA, with a few exceptions in the mining and transportation industries and a few public employers. For more information regarding OSHA standards, see the OSHA website through the Department of Labor: https://www.osha.gov/ Mine safety is regulated through the Mine Safety and Health Administration.
Summary: Watch others work. Eliminate allergens. Adjust your workspace. Speak to your boss or supervisor about your concerns.

In one sentence, describe what the following article is about: Fittings are secured with crimp rings, so it can be difficult to remove the latter without damaging the former. Start by gripping 1 side of the fitting with the open mouth of a pair of pliers. Clamp them down on the PEX piping as closely to the fitting as possible. The pliers will allow you to cut closely to the fitting but prevent you from cutting down onto it. With your free hand, place the open mouth of your PEX cutter over the tubing, on the other side of the fitting. The tool should be right next to the pliers, leaving just enough space to accommodate the fitting. Squeeze the tool to cut through the PEX piping. Keep the PEX tubing in place with the pliers. Put down the PEX cutter and pick up a PEX crimp ring cutter with that hand. Place the fat part of the mouth of the cutter on top of the crimp ring, leaving the skinny part underneath it. Slowly squeeze the handles until the blade at the top cuts though the ring.
Summary: Clamp a pair of pliers beside the fitting. Position your PEX cutter on the opposite side of the fitting and cut. Use a PEX crimp ring cutter to remove the ring.

In one sentence, describe what the following article is about: Your lens will accumulate dust after sitting out for a while, and it's best to remove the dust before wiping off the lens. A few shots of air should be enough to clean off any dust on the lens. Cans of compressed air are available at most electronic supply shops and hardware stores. The can should come with a thin straw that can be inserted in the spray spout for greater accuracy. An optical lens microfiber cloth, like those used to clean eyeglasses, is ideal. Never use liquid cleaners or water on your lenses, as moisture can damage the electronic components. Use the microfiber cloth to wipe a small circle in the center of the lens. Then wipe in increasingly larger circles until you reach the outer edge of the lens. Do this 2 or 3 times if necessary. If you want to protect your lenses from dust and oils, it can be a good idea to use plastic protectors like those used on phone screens. You can do this by buying phone screen protectors and cutting them to fit the shape of your lenses. Change them whenever they become dirty, streaked or dusty.
Summary:
Use compressed air to clear any dust from the lens. Wipe the lens with a dry microfiber cloth. Start in the center of the lens and wipe in a circular motion. Cut phone screen protectors to fit the lenses for extra protection.
