Effects of long-term or repeated exposure Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged inhalation may cause effects on the lungs. Risk of tooth erosion upon repeated or prolongated exposure to an aerosol of this substance. Mists of this strong inorganic acid are carcinogenic to humans. See Notes.

The use of intellectual property generates non-routine profits. Those are often an order-of-magnitude greater than routine earnings.[2] Non-routine profits are essential to warrant the high investments needed for high-technology industries.

Earnings are the net benefits of a corporation's operation.[1] Earnings is also the amount on which corporate tax is due. For an analysis of specific aspects of corporate operations several more specific terms are used as EBIT (earnings before interest and taxes) and EBITDA (earnings before interest, taxes, depreciation, and amortization).
Some statistical models (e.g. based on Benford's law or Beneish M-score) are used in order to detect possible earnings manipulations (fraud).
Chemical dangers Decomposes on heating. This produces toxic and corrosive gases including sulfur oxides. The substance is a strong oxidant. It reacts with combustible and reducing materials and organic materials. This generates fire and explosion hazard. The substance is a strong acid. It reacts violently with bases and is corrosive to most common metals forming a flammable/explosive gas (hydrogen - see ICSC 0001). Reacts violently with water. This generates heat and fire or explosion hazard. See Notes. Attacks many plastics.
Routes of exposure Serious local effects by all routes of exposure. The substance can be absorbed into the body by inhalation of its aerosol. Effects of short-term exposure The substance is very corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Exposure could cause asphyxiation due to swelling in the throat. Inhalation of high concentrations may cause lung oedema, but only after initial corrosive effects on the eyes and the upper respiratory tract have become manifest. Inhalation may cause asthma-like reactions (RADS). Medical observation is indicated. See Notes.

Many alternative terms for earnings are in common use, such as income and profit. These terms in turn have a variety of definitions, depending on their context and the objectives of the authors. For instance, the IRS uses the term profit to describe earnings, whereas for the corporation the profit it reports is the amount left after taxes are taken out.
Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. Effects of long-term or repeated exposure Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged inhalation may cause effects on the lungs. Risk of tooth erosion upon repeated or prolongated exposure to an aerosol of this substance. Mists of this strong inorganic acid are carcinogenic to humans. See Notes.
