Subsidies by governments - what about safety investment?

In an article today, I understood where the huge amounts of subsidies allocated/borne by the government are utilized. Some amount goes to help the poor / middle class people. In this, some amount is also being spent on those who does not deserve because of their high income but possibly because of the difficulty in providing targeted distribution system, such leakages are happening. It is stated that Rs 5,29,000 crore is being the tax breaks given by the government to the corporations, which result is reduced cost of production thus the cost of product sold in the market.
I feel government should also include provision for exemptions on the money spent to improve safety in the work place. And while filing their tax returns, they should include the safety performance by way cost of the accidents (direct and indirect) and this much should be penalized for poor safety. This equivalent amount should be credited in to safety promotion fund account managed by the government for appropriate use. And those who do not incur any cost due to accidents, government can give some exemption either a % of their profits or the amount spent on safety betterment as safety reward by proper adjustment in balance sheets.
I am not an economist, but I feel such measures help in improving safety for the workers in the company.
