There's no such phenomena as negative DC.
Minus sign only means, that current is flowing the other way than you are measuring.
It's danger is exactly the same as "positive" DC.

What color is green positive or negative for DC?
green is ground regardless of ac or dc
What is negative 48 volt DC voltage?
Negative 48 volt DC voltage is simply a voltage that is negative 48 volts with respect to ground. This voltage is widely used in telecommunication systems.
What is the difference of DC and pulsating DC?
DC: constant current in the forward directionPulsating DC: An AC signal which has it's negative components blockedA: The terminology applies to a VALUE of DC being interrupted by its absence periodically or random
What is frequency of dc?
You can say DC voltage has a frequency of zero Hz.Because it is unidirectional in nature (may be positive or negative)
Which is more dangerous AC or DC?
I am not 100% sure but I think DC is more dangerous than AC.Both are dangerous. It is difficult to put numbers on it, as there are too many variables which determine the amount of current which flows through you when you get a shock. There is only one safe course when dealing with electricity, and that is to assume it is always dangerous and always avoid touching anything live.
Is DC dangerous?
There's no such phenomena as negative DC. Minus sign only means, that current is flowing the other way than you are measuring. It's danger is exactly the same as "positive" DC.
Why all telecom dc powered equipment is designed with negative inputs like -48 -60?
AC currents alternate from AC to DC in a constant wave. The DC current is a direct and consistent current demonstrated to the negative reading. AC traveling from negative to positive and DC traveling in negative.

Negative 48 volt DC voltage is simply a voltage that is negative 48 volts with respect to ground. This voltage is widely used in telecommunication systems.
Which is more dangerous ac or DC shock?
DC is more dangerous because its magnitude doen't goes zero instantly after every half cycle as in case of AC .
Can one get shocked by DC voltage?
unfortunately yes! A DC voltage is potentially more dangerous than an AC voltage due to the fact that ac swings from positive to negative and therefore passing zero volts in the process. If you were say, holding a piece of metal with AC across it you have more chance of letting go than holding the same piece with DC across it. DC is "constantly on" if you like... be careful!
Was Washington DC named most dangerous city in 2009?
no
What is a negative risk?
A negative risk is something that is a bad or dangerous risk to take.
What is the difference of DC and pulsating DC?
DC: constant current in the forward directionPulsating DC: An AC signal which has it's negative components blockedA: The terminology applies to a VALUE of DC being interrupted by its absence periodically or random
Why ac current is more dangerous than dc?
no actually dc current is more dangerous than ac because dc is a direct current and has no current zero condition ,which is very dangerous and do not leave us if we get shock while ac current leave us when we get shock
What is a positive and negative connotation for dangerous?
Positive connotation: Exciting Negative connotation: Risky
