Falling in the last category is Denmark's own Crown Princess Mary. She has two tiaras: the Ruby Parure tiara (which she last wore at Crown Princess Victoria's wedding), and her wedding tiara. Every now and then, she'll bust out a third, the Midnight Tiara (which we saw during Queen Margrethe's birthday celebrations), but that one is a loaner.
The General Duty Clause has an important use for workers. Sometimes there is a hazard, but OSHA has no specific rule or standard dealing with it. Under the General Duty Clause, the employer has an obligation to protect workers from serious and recognized workplace hazards even where there is no standard.
Under the OSH Act, employers are responsible for providing a safe and healthful workplace. OSHA's mission is to assure safe and healthful workplaces by setting and enforcing standards, and by providing training, outreach, education and assistance. Employers must comply with all applicable OSHA standards.
